Preserving the deduped advantage while mirror-copy ing a Hammer PFS

[Siju George]

Hi,I got a new hardware and I was migrating the PFSes to the new disks.My PFSes on the old disks are deduped and some are with ratio more than 2.5. They also have many snapshots.When I mirror-copy them to the new disks they expand and I have dedup them again. 

Is there any way to preserve the deduped effect during a mirror-copy?Thanks--Siju
