Installing Maintenance Releases

If a feature release (formerly "service pack") is already installed and a maintenance release (formerly "hotfix pack") is made available after the feature release, you can download the maintenance release on the CommServe computer and use the CommCell Console to install hotfixes on your clients.

Before You Begin

Download the maintenance release by selecting one of the following scenarios that applies to your CommCell environment.

Note: If you need to download cumulative hotfixes, follow the "CommServe computer does not have Internet connectivity" download steps.

  1. From the CommCell Console ribbon, on the Tools tab, click Add/Remove SoftwareUpdate Software.

    If you want to install the maintenance release on a CommServe computer configured in a cluster environment, right-click the CommServe node and then click All Tasks > Add/Remove Software > Update Software.

  2. In the Update Software dialog box, expand Client Computers, and then select the clients on which you want to install the hotfixes.
  3. Click OK.

    You can track the progress of the job from the Job Controller window.

Note: During a maintenance release installation, services are stopped and the CommCell Console is closed on affected machines. After installation, services may be cycled.


  • Hotfixes are installed on the selected clients.
  • If you selected the options to install Windows OS updates and MS SQL Server updates when you install Commvault feature release or maintenance release updates, then these updates are installed on the select clients. To see the updates that are installed, see "Results" in Installing a Feature Release Remotely Using the CommCell Console.
