The PowerMaxOS 5978 Q3 2019 SR along with Solutions Enabler 9.1, Unisphere 9.1, and REST API 9.1 introduce the ability to create native SnapVX and legacy mode sessions from the same source volume. This can be used either as a short-term solution to maintain existing snaps/clones while transitioning from one mode to another, or as a continuous solution to provide an application with key benefits from the various session types. For example, to create a Clone of a database that is already being protected by regularly scheduled SnapVX snapshots.
Interoperability is not allowed when cascading sessions. For example, a SnapVX snapshot cannot be taken from a Clone target. Interoperability is also limited during restore operations; legacy mode sessions cannot be created if a native SnapVX snapshot is in a restore state, and conversely.
