Celerra Replicator with common base checkpoints

Hello replication experts!

For clarification I have a quesiton related to Celerra filesystem replication with common base checkpoints, aslo called "incremental attach replication".

All steps of this procedure are well explained in the Celerra Replicator documentation.

But I would like to verify just for the peace of mind.

Particularly, after  I successfully refresh - "nas_replicate -refresh -source -destination ",

but before I delete old replication session, I would like to verify the fact that source and destination checkpoints have common base and the same view of filesystems.

Any suggesitons? Thanks in advance.
