You can update Commvault platform releases and maintenance releases.
-
A platform release (formerly "feature release") is a collection of new features, enhancements to existing features, and enhancements for product stabilization. Each platform release also contains a cumulative set of hotfixes that were released after the previous platform release version. New platform releases are available every 6 months. Each platform release undergoes full regression testing prior to release.
To keep your CommCell environment up to date, we recommend that you update the platform release every 1 to 2 years.

A maintenance release 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.
