Which migration options are supported when upgrading from 32-bit to 64-bit: combination of qtrees via QSM and volumes via ndmpcopy corresponds to which option?

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

Answer: (D)

The supported upgrade path combines two separate migration methods: use QSM to move qtrees and use NDMP copy to move volumes. QSM is designed to migrate individual qtrees within the namespace, while NDMP copy handles whole volumes, which is necessary for moving the larger data structures intact during a 32-bit to 64-bit upgrade. SnapMirror is primarily for replication purposes and isn’t the recommended method for migrating the data structures involved in this upgrade. Therefore, the correct approach is to perform both migrations—qtrees via QSM and volumes via NDMP copy—together.
