You can upgrade an existing high availability standby CommServe server which was setup using a previous service pack.

Step 1: Upgrade Instance 1 (CommServe Client) to the Current Service Pack

Step 4: Delete the Commvault SQL Instance

  • Note down the SQL Undo File Path folder from the SQL Restore Schedule associated with LiveSync operation.
  • Delete the Commvault SQL Instance in the CommCell Console.
  • Delete the SQL Undo File Path folder.

Step 5: Reinstall Instance 2 (SQL Client)

The SQL Server Agent and the CommServe Failover package must be installed as a second instance. For more information on installing the CommServe Failover package, see Installing the CommServe Failover Package.

Step 6: Uninstall Instance 1 and Instance 2 on the Standby CommServe Host

Step 9: Verify the Default Setup

Verify the setup from the production CommServe host to ensure that the default components are installed and configured properly. For more information, see Verifying the Default Setup.

What to Do Next

  • Perform a production failover to switch the CommServe server from the currently active CommServe host to a standby CommServe host. For more information on performing production failovers, see Performing Production Failovers.
  • Remove the Remote Software cache on the second instance, if it was previously configured.

    Service Packs must be installed on the production and standby CommServe hosts using the process described in Installing Service Packs On High Availability CommServe Hosts.
