Removing a service pack

Last Updated : Nov 21, 2024 |

About this task

The service pack removal procedure downgrades your software to the previous software version.

If you follow this procedure, do not have to reconfigure or reprovision the system. All system configuration and application data is preserved.

Remove service packs during scheduled maintenance times.

Perform the following procedure to remove an installed service pack from your system:

Note:

Some of the steps in this procedure are specific to the Avaya Aura® MS EM. If you are using a different management system, your actions will be different for those steps.

Before you begin

Before proceeding with the software removal, ensure that you:

  • Obtain the installer for the earlier software release. When uninstalling and preserving data to remove a service pack, you can only go back to the previously installed software version. You cannot install a version older than the software previously installed because the data is not compatible.

  • Back up your system.

    In case of unforeseen problems during the downgrade, you can use the backup to restore your system to the previous configuration.

  • Remove service packs one node at a time in a cluster configuration. The other nodes in the cluster maintain service.

  • Remove the service pack from the standby server first and then remove the service pack from the active server when upgrading High Availability server pairs.

Procedure

  1. Prevent new sessions from starting on the system by navigating to EM > System Status > Element Status > More Actions > Pending Lock.
  2. Click Confirm.
  3. Check for active sessions on the server by navigating to EM > System Status > Monitoring > Active Sessions. Wait for the active sessions to end. The system automatically changes to the Locked state after all the sessions have ended. Perform the following steps if you want to continue before the active sessions end:
    1. Manually lock Avaya Aura® MS, by navigating to EM > System Status > Element Status and clicking More Actions > Lock. Locking the media server also ends any remaining sessions.
    2. Click Confirm.
  4. After the system ends the sessions, stop Avaya Aura® MS by navigating toEM > System Status > Element Statusand clicking Stop.
  5. Click Confirm.
  6. Before uninstalling Avaya Aura® MS, you must uninstall Avaya Aura® MS packaged applications that are listed underEM > Applications > Packaged Applications.

    See the application documentation for the detailed uninstallation procedures.

    Ensure that you select the preserve data option, if applicable to your applications.

    Important:

    You lose all the data if you do not accept the default action to preserve application data.

  7. Uninstall the current Avaya Aura® MS installation but ensure that you select the option to preserve system configuration and application content data.
    Important:

    You lose all the data if you do not accept the default action to preserve system configuration and application content data.

  8. Uninstall the media server software by using the following command:

    • Linux®:

      In a Linux® shell type:

      installpath/UninstallMediaServer/UninstallMediaServer
  9. If the system prompts for restart, then restart the system after the uninstallation process is complete. .
  10. As a Linux® root user, navigate the file system to locate the installer and run the installer as follows:

    • Linux®: ./MediaServer_10.2.0.39_2024.09.23.bin

    The installer automatically detects the preserved configuration and application content data. Therefore, the system does not prompt you to choose an installation location or to reselect any other options. The installer uses the original location and selections.

  11. Follow the prompts to exit the installer.
  12. Install each application by running the installation for each application.

    For application installation procedures, see application documentation.

  13. Open EM and navigate to EM > Tools > Manage Software > Inventory.
  14. Verify whether the software versions listed are correct.
  15. If at any time the system prompted you for a restart but you deferred the restart, restart your system now.
  16. After the system restarts, open EM.
  17. Check for any service-impacting alarms and perform an appropriate test of the system, for example, place a call to the application.
