text: Figure 7-46 Volume copy after migration 
  
  The volume copy is now migrated without any host or application downtime to the new 
  storage pool. 
  
  Another way to migrate single-copy volumes to another pool is to use the volume copy 
  feature, as described in 7.7.2, “Volume migration by adding a volume copy” on page 285. 
  
  **Note:**Migrating a volume between storage pools with different extent sizes is*not*
  supported. If you need to migrate a volume to a storage pool with a different extent size, 
  use the volume copy feature instead.
