I have an mtree that is being replicated between Data Domains in two data centers (DD1 => DD2).  I need to move the destination mtree from one DD to another in the same data center (DD2 => DD3).  FYI - all systems are DD9500s. 

To accomplish this, I started by configuring cascading replication so the mtree that is replicated from DD1 to DD2 is then replicated to DD3 (DD1 => DD2 => DD3).  This was successfully initialized and now all three mtrees are fully synced.

Now I need to figure out the next steps.  Here is what I am planning:

1. Disable & delete both replication pairs, DD1 => DD2, and DD2 => DD3;
2. Create & enable replication from DD1 => DD3;
3. Once the new replication pair is fully initialized and synced, delete the mtree on DD2 to recover the capacity.

I'm hoping, but I'm not certain that since the mtree replica on DD3 is already a copy of the original mtree on DD1 that the initialization and sync will go fairly quickly (we're talking about ~92TB of data - after dedupe and compression).

Is this the right way to do this or is there a better approach?

Thanks in advance
