21. You have designed a CDMS migration to migrate from a NetApp filer to a Celerra NSX. All filesystems are being used by NFS and CIFS clients. Which migration method scenario would allow you to migrate both NFS and CIFS security and permissions along with the data?

A. Use CDMS to copy the NFS data and then run CDMS a second time to copy the CIFS data

B. Use EMCopy to migrate the NFS data and permissions and then run it again to move the CIFS permissions and security

C. Use rsync to copy the NFS data and permissions. When finished, use EMCopy to copy the CIFS permissions and security.

D. Use CDMS with CIFS to migrate the data and NFS permissions will migrate by default because the Celerra stores filesystems in a UxFS

Answer: C
