• Question 11:

  An administrator wants to migrate an FLR-enabled file system with DHSM-enabled from a Dell EMC VNX array to a new Dell EMC Unity XT array. What method should they use?

  A. IP Replicator to replicate the file system

  B. Dell EMC Unity File Import feature

  C. IP Replicator V2 to replicate the file system

  D. CTA with Unity XT FLR-enabled FS as a tiering destination

  Correct Answer: B

  FLR is supported when using Native File Import to migrate fromVNX to Unity.

  If the source file system is FLR-enabled, the destination is provisioned with the same FLR settings

  No ability to reconfigure FLR settings during importRetention periods and lock status are migrated.

  If an FLR file system is being imported, DHSM must be configured on the VNX
