The data migration begins automatically after the MDisk is imported successfully as an 
image-mode volume. You can check the migration progress by clicking the task under 
Running Tasks, as shown in Figure 6-61.

After the migration is completed, the volume is available in the chosen destination pool. 
This volume is no longer an image-mode volume. It is now virtualized by the system.
At this point, all data has been migrated off the source MDisk, and the MDisk has switched 
its mode, as shown in Figure 6-62. 
The MDisk can be removed from the migration pool. It returns in the list of external MDisks 
and can be used as a regular MDisk to host volumes, or the legacy storage device can be 
decommissioned.
