Once a VNX VDM is imported as a NAS Server into a Dell Unity system, the destination NAS Server and the file systems under it can participate in a replication session. Once the destination NAS Server and file systems are created on Unity system as part of the file import session, the destination NAS Server can be replicated to a system running Dell UnityOS version 4.0 and later. For more information about File Import, please review the white paper titled Dell Unity: Migration Technologies on Dell Technologies Info Hub.
