Restoring the earlier version of the Presentation Server if the upgrade fails

Use this topic to understand how to restore the TrueSight Presentation Server to the earlier version if upgrade fails.

When you upgrade the TrueSight Presentation Server to 11.3.04, the installer automatically backs up the installation and configuration files of the Presentation Server 11.3.xx, 11.0, and 10.7 installation in one of the following folders:

• 11.3.0x
  • (Microsoft Windows) installationDirectory\truesightpserver_11.3.xx
  • (Linux) installationDirectory/truesightpserver_11.3.xx
• 11.0
  
  • (Microsoft Windows) installationDirectory\truesightpserver_11.0.00
  • (Linux) installationDirectory/truesightpserver_11.0.00
• 10.7
  
  • (Microsoft Windows) installationDirectory\truesightpserver_10.7.00
  • (Linux) installationDirectory/truesightpserver_10.7.00

The installer copies all the installation and configuration files of the TrueSight Presentation Server 11.3.04 installation in the following folder:

• (Microsoft Windows) installationDirectory\truesightpserver
• (Linux) installationDirectory/truesightpserver

To restore the earlier version of the TrueSight Presentation Server

1. Stop the TrueSight Presentation Server if it is running.
2. Delete the new truesightpserver folder.
3. Rename the truesightpserver_x.x.xx folder as truesightpserver. For example, rename truesightpserver_11.3.xx as truesightpserver.
   If you are operating in a Linux environment, go to step 5.

4. (Microsoft Windows) Open regedit and edit the display version settings stored in the following Windows registry key to 11.x.xx or 10.7.00:

   KEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\TrueSightPServer
5. Start the TrueSight Presentation Server.
6. Reimport the CMA repository after the TrueSight Presentation Server is up and running.
