Dell UnityOS version 4.1 introduced Dell Unity native SAN copy import and file import. These features provide an automated method for migrating block storage resources, such as LUNs and consistency groups, and NFSv3 file systems mounted on a virtual data mover (VDM) from a VNX1/VNX2 storage system to a Dell Unity system. Dell UnityOS version 4.2 introduced support for CIFS-based file systems mounted on a VDM. In Dell UnityOS version 5.1, file import has been extended to include multiprotocol virtual data movers. When selecting the target pool for the import session, both Traditional and dynamic pools are supported. To further distinguish the different pools on the system, a Type field was added to the pool selection window to easily differentiate pool types.
