Hi ,
 
We are migrating  data from a FAS 8200 to Metro cluster . on FAS 8200 all volumes are compressed and dedup  on target system we have not enabled of storage efficiency . with vol compression we have good  storage saving on the source vol . 
 
- Compressed vol after migration to a  non- compressed volume ,  will it  rehydration . ?
 - when  compressed data is access/modified , will be stored in compressed ?
 
thanks
