Alright, but for copypool, you can't define a nextstgpool.
I think that the best is to migrate the primary pools with any technique you 
want (migration, reclamation, move data, move nodedata,..) and, when finished, 
to delete all volume in the olds copy pools.

Easiest way IMO is to set the new library's storage pools as the nextmigration 
pool for your old stuff. You can then kick off migration and let it move stuff 
over for you.

So updating your old 'offsite' pool to include the new 'offsite' pool as the 
next migration pool. Make sense? Then manually kick off migration and wait till 
its done.
