Hi Avilt,  From what i understand, as long as you don't delete the replication job, you won't lose the checkpoints used to perform the replication. A high level workflow for the move in my opinion would be something like this:  1. Stop the replication on both the source and destination, prior to shutdown (this would be critical. You wouldn't want to shutdown in the middle of a replication) 2. Shutdown 3. Relocate, and change IP address of Control Station 4. Log into control station and Change IP addresses of interfaces on DataMover 5. Re-estable trust either by using nas_cel or the the Gui, under Celerra Network Servers 6. Edit the DataMover Interconnect to use the correct ip addresses 7. Validate the DataMover Interconnect 8. Start the replication  If i were you, i'd open a support call with EMC, and ask them to validate those steps before you put them into concrete as an action plan.
We have a replication setup between two NS20 devices which is working fine. Now due to Data center migration, we will be moving the remote NS20 device to a different location and as a result I need to change the IP addresses (control station, data mover, CIFS server). Now what will happen to the replicated data on the remote device? Can I continue the replication just by changing the IP addresses?
