In the autumn of 2020, the social entertainment platform Hago was riding a wave of success. Millions of users across Southeast Asia and Latin America were logging in daily not just to chat, but to play embedded social games like Hago Play Together, Ludo, and Bingo. The development team, based in Singapore and Shenzhen, knew that user retention depended on seamless updates.

On a Tuesday morning, the product manager, Lin, finalized the changelog for version 3.17.0. The update was significant. It promised three major features:

  1. "Super Res" Voice Mode – A new audio codec that reduced lag during group voice chats in noisy game rooms.
  2. Mini-Profile Cards – A UI overhaul allowing users to peek at others’ stats without leaving a game lobby.
  3. Offline Gift Queue – A long-requested feature where virtual gifts (like "Flying Hearts" and "Racing Cars") would send later if your connection dropped.

The engineers had squashed a critical bug from v3.16.2 where the "Lucky Dice" game crashed on certain Android 10 devices. Now, the build was signed, tested, and ready.

The Download Push

By Thursday at 10:00 AM GMT+8, the v3.17.0 APK was live on the Google Play Store. Simultaneously, Hago’s in-app update system triggered a "soft prompt" – a non-intrusive banner that read: "New version ready. Faster voice + better gifts. Download now."

Users on poor 3G networks in rural Indonesia or Brazil saw a different screen: a streamlined "Light Download" option that installed only the core chat and lobby features first, fetching high-res assets later. This was new in v3.17.0.

Within six hours, over 500,000 users had updated. A popular Filipino streamer, "MitchGamez," went live on Hago to test the update. She shouted into her mic, "Guys, the delay is gone!" Her chat exploded with "v3.17.0" spam.

The Bumpy Patch

Not everything was perfect. By day two, bug reports trickled in. Some users with Xiaomi phones found that after the download, the "Offline Gift Queue" would show phantom gifts that never arrived. Lin’s team immediately pushed a hotfix (v3.17.1) without requiring a full download – a "delta update" that patched only the changed code.

Why It Mattered

The v3.17.0 download wasn't just about new features; it was about trust. Hago had learned that every 1 MB of unnecessary size reduced downloads by 0.5% in emerging markets. The team had optimized the APK from 78 MB to 64 MB for this release.

By the end of the month, v3.17.0 had been downloaded over 12 million times. The "Super Res Voice" mode became the new default, and the "Offline Gift Queue" reduced failed transactions by 22%.

For users, it was a simple "Update" button. For Lin and her team, it was the result of 300 hours of coding, 15 device lab tests, and a single moment of relief when the download servers didn't crash.

Key Takeaways from the v3.17.0 Hago Download:

If you were a Hago user in late 2020, you likely clicked that "Download" button without a second thought – but behind it was a carefully orchestrated launch designed to keep your party games going, no matter where you were.

Searching for the v 3.17.0 Hago download allows you to access a classic version of this popular social gaming platform. Known for its unique blend of mini-games, voice chat rooms, and live streaming, Hago has evolved significantly since the 3.17.0 release, with current versions reaching up to 5.44.0 as of April 2026.

Title: The Ghost in Version 3.17.0

The rain in Jakarta hammered against the windowpane of Rizky’s apartment, a relentless rhythm that matched the frantic tapping of his thumbs against his smartphone screen. It was 2:00 AM, and the city slept, but Rizky was awake, hunting for a digital ghost.

For weeks, the online forums had been buzzing with whispers. They spoke of Hago v 3.17.0—a version of the popular social gaming app that supposedly existed for only a few hours before being scrubbed from the servers. It wasn't listed on the Play Store, nor the official site. It was an "APK phantom," a build that reportedly contained a hidden game mode called The Mirror Room.

Rizky, a 22-year-old computer science student and avid Hago user, was obsessed. He had spent three nights trawling through third-party APK repositories, dodging fake links and malware, determined to find the authentic file.

"Got you," he whispered.

Buried on a forgotten Czech server, behind a wall of expired captchas, was the file: Hago_v3.17.0_release.apk. The file size was slightly larger than the current public version (v3.18.2). That was the first anomaly. Why would an older version be heavier?

He initiated the download.

The progress bar crawled. 10%. 20%. The rain outside intensified, drowning out the hum of his laptop. At 99%, the screen flickered—not the phone screen, but the laptop screen he was mirroring it to. The file completed.

Rizky transferred the APK to his phone. He took a breath, sipped his cold coffee, and tapped Install.

Warning: Unknown Source. He enabled it. Installing...

The app icon appeared. It looked the same—the colorful speech bubble logo—but when he opened it, the loading screen was different. The usual upbeat jingle was distorted, slowed down by half a speed, sounding like a dirge played in a cavern. Hago (an abbreviation for "Have a Good One")

Welcome to Hago v 3.17.0.

The interface loaded. It was the familiar lobby of chat rooms and mini-games, but the colors were desaturated. The usually vibrant avatars of other users were greyed out, moving stiffly like puppets with half their strings cut.

Rizky navigated to the game selection menu. Sheep Fight, Knife Hit, Ludo... all the standard games were there. But at the very bottom of the list, past the scroll limit, was a game icon that was simply a black rectangle with a white question mark.

He tapped it.

A pop-up appeared: "The Mirror Room requires 2 players. Finding opponent..."

"Searching for nearby users..." the text blinked.

Rizky lived alone. His nearest neighbor was three floors down. Yet, the app pinged instantly.

Opponent Found: User_0x00.

The game launched. It wasn't a game Rizky recognized. The screen split in half. On the top was his phone's front-facing camera feed—his own tired face illuminated by the blue light of the screen.

On the bottom half was the opponent’s feed.

Rizky froze.

The opponent wasn't a person. The feed showed a dark room, lit only by a blue light. It was Rizky’s room. It was his room. But the perspective was from the corner, near the ceiling. He could see the back of his own head, hunched over the phone.

He spun around, looking at the corner of the ceiling. Nothing. Just shadows and drywall.

He looked back at the screen. The "Opponent" view shifted. The camera was moving. It was descending from the ceiling, drifting slowly toward him.

A chat box overlay appeared. User_0x00: Don't look back. Just play.

Rizky’s hands trembled. The objective of the "game" appeared: Maintain Eye Contact.

The timer started. 3:00.

On the screen, the figure in the opponent's video feed—a shadowy silhouette that looked disturbingly like Rizky—was getting closer to the "camera" (which was seemingly right behind him in the real world).

Rizky stared intensely at his own image on the top screen, terrified to look away from the phone. He could hear the rain outside, but now, underneath the rain, he heard the distinct creak of a floorboard behind him.

One minute left.

The video feed on the bottom half was now right over his shoulder. He could see the hairs on the back of his neck standing up in the digital reflection.

User_0x00: I am waiting for the update.

The phone vibrated violently. The screen glitched, turning a deep shade of crimson. The timer hit zero.

GAME OVER.

The screen went black. Then, a notification banner slid down from the top of his phone's OS.

Update Available: v 3.18.2. Would you like to fix the bug?

Rizky’s finger hovered over the 'Install' button. The creaking sound behind him stopped. He slowly turned around, expecting to see the entity from the video feed.

The room was empty. Just his unmade bed and the rain against the window.

He let out a shaky breath, realizing he had been holding it the entire time. It was a prank. An elaborate, terrifying augmented reality prank built into a leaked beta version. Someone had hacked the app to scare users.

He laughed nervously, the sound hollow in the quiet room. He decided to delete the app immediately.

He went to Settings > Apps > Hago.

But when he tapped the icon to uninstall, the button didn't say "Uninstall." It was greyed out. The text read: "System Application. Cannot Remove."

Suddenly, the phone’s camera app opened on its own. The viewfinder showed his room, live. In the center of the frame, standing right where he had been sitting, was a digital overlay. It was a Hago avatar, but it had Rizky’s face, staring blankly.

A text message arrived from an unknown number. It contained a link. Link: v 3.18.0 download. The update is never finished.

Rizky threw the phone onto the bed. He backed away toward the door. As his hand touched the doorknob, his phone lit up one last time. The sound of the Hago notification jingle rang out, crisp and clear, cutting through the storm.

He looked at the screen.

User_0x00 has invited you to a voice chat.

Accept? [Yes] [Yes]

There was no "No" button.

Rizky didn't wait to see what would happen if he answered. He wrenched the door open and ran into the hallway, leaving the phone behind, still glowing with that cursed version number: v 3.17.0.

Inside the empty apartment, the phone screen dimmed, then turned off. In the reflection of the black glass, a figure stood by the window, watching the door close. Identify the Project or Software : Make sure

3.1 Purpose of this document

This document describes the EWA Admin Tool Interface of EWA net which is used to update, manage and maintain the WIS and EPC Databases as well as managing the state of the server.

3.2 Introduction

Besides the software installation, the applications need to have access to certain databases for content data. This content is not installed within the setup of the software but needs to be updated after installation. The aim of this behavior is to decouple software and data update and minimize the downtime of the applications.

This document describes the use and function of the EWA Admin Tool. The following use cases are documented in this description:

V 3.17.0 Hago Download Verified ⟶

The EWA net Administration tool can be started using the favorites menu inside the Internet Explorer. This entry is created during installation and is only available on the server.

v 3.17.0 hago download

Picture 1: Start of EWA net Administration tool using the favorites menu

The EWA net Administration tool can be only started on the EWA net server. If the link to this tool is not available, it can be started manually using the command

[EWA_HOME]\ewa_admin\EWAAdmin.exe

where EWA_HOME need to be replaced with the directory where EWA net was installed.

V 3.17.0 Hago Download Verified ⟶

With the EWA Administration Tool it is possible to influence the availability of the server and see if it is running. The Administration tool acts as a service monitor and shows if the needed Windows services are running or not.

v 3.17.0 hago download

Picture 2: Service Monitor Page for the Server

Within this panel the EWA net server (application server) can be started and stopped. This is more or less a shortcut for the Windows “Services” view.

Also within this panel the user management database (i.e. for specific user data, FIN Cache,…) can be started and stopped.

Note:
Database “start” and “stop” is not simply starting and stopping services. A “stop” always also stops the corresponding TransBase multiplexer service. And “start” always starts both the database engine and the TransBase multiplexer service.

If the services are stopped the application server will not be available for all users. Please take this into account when starting or stopping services.

V 3.17.0 Hago Download Verified ⟶

The databases of WIS net and EPC net are maintained in a very similar way. Since there is no difference except the starting tab on the dialog, both parts will be described in a single chapter

6.1 Influence the installed Database status

On the EPC net / WIS net Screen in the Administration Tool it is possible to see the current state of the running database. If no database is installed, the traffic light will be off. If the database itself is working and the database service shows a good status, it will show a green traffic light. Else the traffic light will show a red status.

Use the “Start” and “Stop” Buttons to shutdown / start the database and the Transbase service.

Note:
Database “start” and “stop” is not simply starting and stopping services. A “stop” always also stops the corresponding TransBase multiplexer service. And “start” always starts both the database engine and the TransBase multiplexer service.

Picture 3: EPC net Administration of Database

6.2 Install new Databases

Note:
EPC net / WIS net database installation requires a valid Start Key entered in the admin interface of EWA net. You can go to the interface either by selecting “EWA net Admin” from your Favorites “EWA net” folder or directly by its URL http://localhost:9000/EWA-net/Admin. An explanation for entering a StartKey is provided in your Admin Guide.

To install a new database into the running application, use the “Install” button. This will start the process of copying the needed database files from DVD to hard disk and attach the databases to the running service. Once a database is installed, the button will be labeled as "Update" to indicate that this action will update the running database.

After the button is pressed, the tool will ask you to insert an EPC net / WIS net data DVD to any DVD drive of your machine. For EpC net it will try to read the “FDARequest.cfg” file which is normally in the folder “MBXX\cfg” of any data DVD. For WIS net the program tries to find the "WISCD000" file in the folder "wis" of the DVD root.

Picture 4: Admin tool requests the data DVD configuration file

If the DVD is inserted just press “OK” - the Tool will search all available drives in PC for the configuration file. If you already had a valid data DVD of EPC net in one of your DVD drives, the tool will have skipped this dialog and started installation immediately.

Note:
If the files should be installed using a network share, use the “Browse…” button and navigate to the corresponding folder on the network share and select the “FDARequest.cfg”/"WISCD000" file in the folder “MBXX\cfg”/"wis" relative from the DVD root.

The Tool will also search all hard drives and mounted Shares for data DVDs.

After the configuration file has been read successfully and the database files could be found, the tool will request to select a target drive for the database content. Select one or more drives where all database files should be copied to and click “OK”. The dialog will also show how much space is required on the destination drive.

v 3.17.0 hago download

Picture 5: Selection of the target drive for database content

The next step in the copy process is to start to copy the ROM files to hard disk. If the source DVD can not be located in any drive of the PC, the Tool will ask for a source for copying the files.

Picture 6: Selection of ROM file source

In this dialog, please select the DVD root directory when the tool requests a file. The path inside the media is searched automatically. If a network share is used as file source, please point to the folder which corresponds to the original DVD root.

The copy process will be visualized with a progress. Please wait until all data has been copied or the Tool asks you for further media.

The difference in the update step is that you are requested to insert the DVD which contains the setup into any DVD drive. During update the normal setup will be called to update software resources. Please select the appropriate folder where the setup.exe is available if the files could not be found automatically.

Note:
When updating the server, you should ensure that no user is using the applications. Users can continue working while database ROM files are being copied to the hard disk. But after finish of this process the server will be shutdown so users might lose important data.

6.4 Delete a Database

Database can easily be deleted from the system by clicking on the “Delete” button. This button will delete the currently active database.

Note:
Be sure that you notify all users to save important data and to log off from the system as they might loose data when the database will be deleted.

6.5 Switching databases

When a database set was updated, the older version will be kept as backup database. With the activate database button it is possible to switch the backup and the active database. The former active database will be kept as backup.

Note:
Be sure that you notify all users to save important data and to log off from the system as they might loose data when switching the database.

6.6 Applying Daily Updates for WIS net Database

6.6.1 Configuration and Manual Run

The WIS net database provides the ability to apply incremental daily updates.

Note:
To use this functionality you need additional files which are supplied via ManageSoft. This is only available if you use the online update mechanism. Additionally your access authorization need to enable this feature in the application.

Picture 10: Start Dialog to configure WIS net Daily Updates

Click on the "Daily Updates..." button to configure the settings for daily updates in WIS net. A dialog will appear and give you additional configuration options. If this button is disabled, the database is not active or the access authorization does not permit the use of daily update data.

Picture 11: Configuration Dialog for Daily Update settings

This dialog provides the following options:

Note:
The configuration for daily updates in Admin Tool does not automatically enable a daily based import of the data. Please take a look to the following chapter how to enable a schedules import by using the Windows Task Scheduler.

6.6.2 Running Daily Imports Scheduled

To run daily imports you need to schedule a job in the Windows Task Scheduler which automatically applies the newest received data to the database. You need to configure manually a Task for running the import (i.e. via
 Start Programs Accessories System Tools Scheduled Tasks.

The executed task needs to run in the folder [EWA_HOME]\wis_case_online_importer.

The executed command is: bin\run_mimport.bat <path> <language>

<path>: Specifies the path (folder) where the import files are located.

<language>: Language code to import to database. the following language codes are supported:

Language CodeLanguage
dGerman
eEnglish
fFrench
iItalian
ndlDutch
sSpanish

Example Call: bin\run_mimport.bat C:\LauncherCache\Common\Daily-update_WISnetDocuments_DE d

Notes:
- If you want to import multiple languages, you need to run the script for each of the languages.
- You cannot call the script with arguments in Windows Scheduled Tasks. Therefore the best is to write your own small script which calls the importer for you. Then simply make this script part of your scheduled tasks.

Sample Windows script importing the German and English documentation updates which you may use as a template for own scripts - simply store it anywhere on your disk and make this a scheduled task. The parameters you have to change according to your local installation have been highlighted. Basically you have to configure the correct EWA net installation folder and the directory where your update packages for the daily updates have been stored.

@echo off
cd "C:\Program Files\EWA net\wis_case_online_importer"
bin\run_mimport.bat "C:\LauncherCache\Common\Daily-update_WISnetDocuments_DE" d bin\run_mimport.bat "C:\LauncherCache\Common\Daily-update_WISnetDocuments_EN" e

6.7 Wiping all Database Content

To wipe out all existing database files for both WIS net and EPC net it is possible to run the EWA Administration tool in a special mode. This mode will remove all installed instances of WIS net / EPC net databases and their metadata.

To clean all databases and all metadata of installed databases run the program and go to the screen of the corresponding application. Hold down the "Ctrl" key which pressing on the "Delete" button of the screen. You need to confirm the question and then all files will be removed.

This chapter is mainly intended for System Integrators who want to make use of the batch mode of the Admin Tool to allow further customizing of the installation update process, one may want to make use of the command line features of the EWA Admin Tool.

Note:
EWA Admin Tool has been developed for the “local” environment where all software components will be installed on one single server. In a distributed environment like the “central” not all of the features described here will work.

To get an overview of the available options, just issue the following command on a command line:

“C:\Program Files\EWA net\ewa_admin\EWAAdmin” /?

This overview will not capture all options. Further options will be available here in the documentation

7.1 Database control

Admin Tool allows starting and shutting down the Transbase databases individually without the need of knowledge about the special characteristics behind it. There are currently 3 databases that can be controlled:

The command line is quite easy. You specify which database you want to operate on and which operation you would like to perform: shutdown or boot. The command line for this is:

EWAAdmin.exe [/core | /wis | /epc] [/boot | /shutdown]

Description:

Parameter

Description

/core

Operate on the EWA user management database

/wis

Operate on the WIS net database

/epc

Operate on the EPC net database

/boot

Boot the specified database

/shutdown

Shutdown the database. This will also invalidate any open connection without reconfirmation.

Example call:

EWAAdmin /wis /shutdown

will shutdown the WIS net database.

Note:
When shutting down databases in most cases it may also make sense to shutdown the application server, too. After doing your maintenance be sure to boot the application server again.
There is no command line in EWAAdmin.exe as this can easily be achieved by issuing the command lines
net stop “EWA net Server”
to stop the application server or
net start “EWA net Server”
to start the application server again. This command must be issued on the server machine where the EWA net application server is running of course.

7.2 Update (Database and Software)

If you want to start an update without the user being forced to start Admin Tool and click some buttons you can easily start the update process from the command line. Simply select the application part you would like to operate on (WIS net or EPC net). Admin Tool will then automatically start the update process for the regarding application.

The command line looks like this:

EWAAdmin.exe [/wis | /epc] [/license licensebits] [/force] [/source Path] [/target Drive]* [/exclude Drive]* [/nofork] [/noswupdate] [/unattended] [/v]

Description:

Parameter

Description

/epc

Update EPC net

/wis

Update WIS net

/license

Optional:
Provide the access authorization bits on the command line. For EPC net this is quite useful as it restricts the number of ROM files to be copied. When this parameter is specified a dedicated access authorization check is skipped.

Note: You cannot provide a crypted StartKey here

/force

Optional:
Enforce the copying of ROM files though they might already be installed on the system. This helps replacing corrupt ROM files.

/source PathOptional:
Defines the source path from where to find and copy the database files. Te source parameter can be specified multiple times if multiple source directories are required.
Besides the specified source paths the program always searched all available drives for the needed files if the file can not be found in the defined source path.
/target Drive

Optional:
Specify a target drive for the ROM files. You can repeat this option for several drives

/nospacecheck

Optional:
Flag to specify whether the free space check on the target drive should be omitted. If specified, the program will not check for sufficient free space on target drive.
/nobuffertuneOptional:
Flags the instance to skip Windows buffering optimizations. In rare cases the file copy speed breaks down during the update process to a few KB/s instead of several MB/s. Initially the program has been optimized to allow fast copy performance without impact of running server. If the file copy of the database media is very slow, this command line option can try to skip the optimizations. Do not use this option if the program is copying in a reasonable speed.
/exclude Drive

Optional:
Explicitly exclude a drive from the list of drives where ROM files are allowed to be stored.

You can repeat this option to specify multiple drives

/noforkOptional:
In a normal call the program copies itself to %TEMP% and executes there. If the process should be watched, this parameter can be used to prohibit the copy of the application to %TEMP%.

Note: When using this option the integrated software update will fail. In this case please call the software update manually!

/noswupdateOptional:
Enforces the program to skip consistency checks and does not run software update during database update.

Note: When using this option you have the possibility to skip a software update when installing new database content. Nevertheless is it highly recommended that you always update the software together with the database update. If you decide to de-couple the software and database installation processes this is fine - but do not forget to update the software, too.
The software update will check which software component versions are installed and only updated components will be refreshed. For not updated components at least the language resource, help and what's new files are updated.
In summary: If you do not run the software update, the users will see old help and what's new files.

/unattendedOptional:
Suppresses confirmation dialogs and allows batch execution of the program
/vOptional:
Enables debug logging for troubleshooting (verbose mode)

Note:
When specifying parameters containing special characters like "-" or "/" please quote those parameters.
Example:
Use
EWAAdmin.exe /source "C:\EWA-net"
instead of
EWAAdmin.exe /source C:\EWA-net
The latter one will fail as the commandline parser will think there is another parameter hidden on the commandline.

7.3 Cleanup database

You can remove any installed databases from the system by the command line, too.

The command line looks like this:

EWAAdmin.exe [/clean | /cleanwis | /cleanepc]

Description:

Parameter

Description

/clean

Removes all (EPC net AND WIS net) databases

/cleanwis

Removes the WIS net database(s)

/cleanepc

Removes the EPC net database(s)

When using the update database options in the Administration tool a process is executed which handles the database update. The following steps are processed during a database update:

  1. Access authorization check
    The current access authorization from the disk is read out and interpreted. If the access authorization is not valid, the update will stop and an error message will be displayed to the user.
    The interpreted access authorization can be overridden using the /license command line parameter
  2. Request for Source Media
    The Administration tool searches for suitable source media. The priority is a source path which was given by command line. If none was specified or nothing was found in this path, the tool looks in all drives for suitable content. If none is found, the user is requested to select a source path or to insert a DVD media.
  3. SW and Data Consistency Check
    The program checks if both WIS and EPC are in use. If both applications are used, then the program checks if a software update will also take place with the data update. If an update is also taking place which is not a "hotfix" update, then the user is requested to insert the media of the other application to show that a consistent update with both medias is possible.
    This step is skipped if the flag /noswupdate is issued.
  4. Check Update Possibilities
    A small program (ewa\setup\checker.exe) is executed on the source media to check if an integrated data and software update is possible with this database release. Depending on the return code of this application, the process can continue or not.
    If the result of this application shows that the integrated update is not possible and e.g. with this data update also the Administration tool program needs to be updated, the user will be requested to have a longer downtime and run the software setup before updating the databases. Software setup is then called by the tool and after successful update it will be re-launched.
    This step is skipped if the flag /noswupdate is issued. In this case you need to ensure that the database can be installed with the current software version!
  5. Read Database Definition
    The database meta information is read by the tool using the descriptor files from the source media.
  6. Read Software Version
    The software version information is read from the source media for later purposes.
    This step is skipped if the flag /noswupdate is issued.
  7. Database Structure Version Check
    The program checks if the new database has a structure version which is sufficient for the software which is installed. If the version is too old, the update of the database will fail and the program will complain.
  8. User Update Confirmation
    The user will be asked to confirm the update to the new database version if this is not the initial database which is installed.
    This confirmation is skipped when running in /unattended mode
  9. Update Lock Collision Check
    It is checked if the current active database is the same like the one which will be installed. In this case the user needs to acknowledge the shutdown of the server additionally since the web server needs to be shut down before copying the files to have the database files not locked.
  10. File Copy
    All needed database files are copied from the source media to the target drive. The user will be asked for the target drive to copy to.
    The target selection can be skipped using the /target parameter
  11. Test Database Files
    The database ROM files which have been copied are tested if copied successful.
  12. Integrated Software Update
    If the media contains a newer software release as currently on the disk, integrated software update will be executed.
    This step will be omitted when using the /noswupdate flag. You need to manual run the software update using the command line [Source]\ewa\setup\setup.exe /u.
  13. Write Database Information to Registry
    Meta information of the new database is written to system registry.
  14. Web Server Shutdown
  15. Database Service Shutdown
  16. Old Database Detach
    The old databases are going to be detached from the Transbase database
  17. Update Registry of Current Database
  18. Launch Pre Installation Hook
    If a pre installation hook is specified, this will be launched.
  19. Attach new Database to Transbase
  20. Launch Post Installation Hook
    If a post installation hook is specified, this will be launched.
  21. Remove Old or Incompatible Versions
    Database backup releases which are too old or are not compatible with the new software are removed from disk. Only one backup version is kept.
  22. Re-Init Internal Objects
  23. Start Database Service
  24. Start Web Server
  25. Clean disk and remove unused files from hard drive
  26. Run actions for Daily Updates (if installation references a WIS net database, access authorization allows this and Daily Update is configured correct)
  27. Show Success Message to User

If the update can proceed using a integrated update (when no major software changes are required) the application server will be down between Step 13 and Step 23. This downtime will be usually around 5 minutes. If the update check in step 4 detects that a longer downtime is required, the application will be unavailable from step 4 until step 23.
