The CSI Driver for PowerMax allows you to upgrade an existing volume from nonreplicated to replicated and from replicated to nonreplicated.
You can enable the Volume Migration feature during installation or update it after installation.
The main concept is to tag an existing PowerMax PersistentVolume with the annotation named migration.storage.dell.com/migrate-to and pass the destination StorageClass as a value (for example, powermax-metro).
