You can upgrade a system from Avaya Aura® MS8.0.x, 10.1.0, or 10.2 to the latest Avaya Aura® MS 10.3 and the upgrade process will preserve the configuration and application data.
If you are replacing the operating system, additional steps are necessary to preserve the media server configuration and application data. These steps should be performed while you are re-imaging the disk to replace the operating system.
Perform upgrades only during the maintenance window or during non-peak usage time.
The upgrade procedures set the operational state to Pending Lock. The purpose of placing Avaya Aura® MS in the Pending Lock state is to ensure that the system does not start any new sessions. After all the sessions on the server have ended, then the server can be upgraded without disruption to any users.
When you are ready to upgrade the server, the operational state is set to Locked, which ends any remaining active sessions.
If the media server is set to Pending Lock before the upgrade maintenance window, then the system ends a minimum number of user sessions, if any.
Note:
Note that Avaya Aura® MS 10.3 only supports Red Hat 9.x. It is recommended that you deploy a new Red Hat 8 server with the same network configuration and follow the Upgrading manually procedure.
