Upgrading the CommServe Computer

You can upgrade the CommServe computer using one of the following methods, based on your requirement.

Important

  • After upgrading the CommServe computer to CPR 2022E (11.28) and above, existing HP-UX clients using Feature Release 11.20 may not be able to communicate with the CommServe computer. Therefore, before upgrading the CommServe computer to CPR 2022E or a later release, you must upgrade all HP-UX clients to Feature Release 11.24 or a later release. For information about end-of-life and deprecated platforms, see End-of-Life, Deprecated, and Extended Support for Platforms.

  • Upgrade the Web Server and Command Center if installed on different client computers, immediately after the CommServe upgrade. For more information, see Upgrading the Clients.

    No separate upgrade is required if the Web Server and Command Center are installed on the CommServe computer itself.

Before You Begin

  • If the existing installed version of MS SQL Server on the Microsoft Failover Cluster Manager is lower than MS SQL Server 2022 CU11, then you must manually upgrade MS SQL Server to at least MS SQL Server 2022 CU11 on all Active nodes and Passive nodes before performing the Commvault upgrade. To obtain the required SQL Server Standard Edition, use the Commvault Download Manager as per Downloading Software for Windows Computers Using the Download Manager, and follow Step 5 to include MS SQL Server.

  • If the existing CommServe environment is a configured Microsoft Failover Cluster, stop the following Commvault application pools hosted on the Internet Information Services (IIS) Manager of all passive nodes of the Microsoft cluster environment before starting the update or upgrade process:

    • ConsoleAppDotNetCore

    • ConsolesAppPool

    • WebSearchProxyApplicationPool

Upgrade to the Latest Platform Release

To upgrade the CommServe computer to the latest platform release, select one of the following upgrade procedures:

Note

  • You can upgrade any version of Commvault to the latest platform release. However, note the following:

    • If the CommServe server is at Service Pack 13 or a previous service pack, and you want to update it to Commvault Platform Release 2022E or later, you must first update it to Feature Release 11.24 or Feature Release 11.26.

    • If the CommServe server is at Service Pack 16 or a previous service pack, and you want to update it to Commvault Platform Release 2023 or a more recent platform release, you must first update the CommServe server to Platform Release 2022E.

  • Commvault recommends installing the most recent LTS platform release. For more information, see Platform Releases.

Upgrade with Hardware Refresh

If your CommServe computer is old or deprecated, you can move the CommServe database to a new hardware during the upgrade. For more information, see CommServe Upgrade with Hardware Refresh.

Upgrade in a Disaster Recovery Environment

If your CommCell environment uses a disaster recovery configuration, you can configure the CommServe LiveSync feature for Disaster Recovery. For more information, see Upgrade in a Disaster Recovery Environment.
