You can update Commvault feature releases and maintenance releases.
Note
The release version is expressed as a combination of the platform release, the feature release, and the maintenance release. For example, a release version of 11.26.22 refers to Platform Release 11, Feature Release 26, and Maintenance Release 22.
-
A feature release (formerly "service pack") is a collection of new features, enhancements to existing features, and enhancements for product stabilization. Each feature release also contains a cumulative set of hotfixes that were released after the previous feature release version. Feature releases are available in a 90-day cycle. Every feature release undergoes full regression testing prior to release.
To keep your CommCell environment up to date, we recommend that you update the feature release every 1 to 2 years.
-
A maintenance release (formerly "hotfix pack") is a collection of hotfixes that are targeted at resolving specific critical issues that might cause major disruptions to operations or potential losses of data. A new maintenance release is available every month.
To keep your CommCell environment up to date, we recommend that you update the maintenance release every 2 to 3 months.
