Which migrations are supported from 32-bit to 64-bit aggregates?

• A. Migration of qtrees via QSM
• B. Migration of volumes via ndmpcopy
• C. Migration of volumes via SnapMirror
• D. Both A and B

Answer: (D)

When moving data from a 32-bit aggregate to a 64-bit aggregate, you have two supported paths: migrating qtrees with QSM and migrating volumes with NDMP copy. QSM can move qtrees between aggregates, preserving their structure and permissions, even when the source is on a 32-bit aggregate and the destination is a 64-bit one. For larger data units represented as volumes, NDMP copy provides a way to transfer the entire volume contents to a destination volume on a 64-bit aggregate. SnapMirror, while great for disaster recovery and ongoing replication, isn’t a one-time migration tool between different aggregate types, so it isn’t used for this purpose. Therefore, both migrating qtrees via QSM and migrating volumes via NDMP copy are supported.
