If you want to perform a full Cloud Manager system backup (excluding the Orchestration components), you can do so at any time prior to the upgrade process. This backup saves all Cloud Manager files and any custom files you might have created for it. This is an optional process; normally, the backup of the Cloud Manager configuration automatically triggered during an upgrade is sufficient for Cloud Manager restoration.
For more information about performing a full backup, see Section 20.1.2, Backing Up the Application Components Prior to Upgrading.
