Deduplication savings on a FlexVol volume are retained when the volume is moved by using the DataMotion for Volumes (volume move) operation. If deduplication operations are running when a volume move operation is active, then these operations are stopped shortly before the final cutover is complete.
After the volume move is complete, the efficiency operations cannot be resumed from the previous checkpoint and the efficiency operations start from the beginning.
If you try to nondisruptively move a FlexVol volume that has deduplication operations running, then the deduplication operation is aborted.
For more information about DataMotion for Volumes, see the Data ONTAP SAN Administration Guide for 7-Mode.
