As needed, Commvault updates the OVA template to include operating system updates and enhancements. To ensure that the access node contains all features and critical security vulnerability fixes, you must decommission the existing client and deploy the latest Access Node and MediaAgent OVA template.
You must also upgrade the CommServe server and Virtual Server Agent to the most recent Commvault service pack or install available HotFixes for the installed service pack. For instructions, see Installing a Feature Release Remotely Using the CommCell Console.
