Hello,
Catalyst is only available for StoreOnce Backup system (old D2D).
Replication capable can only be selected with "Hardware StoreOnce" and this lead to replicate only changed block and of course with no rehydratation.
If you need to copy with rehydratation ... The first question would be what kind of link there is between your two storeonce nodes ?
After the answer we will see what is the best way to proceed .
PS : As your new question is not about object consolidation but the storeonce setup with object copy it would be better to create a new thread.
