Recoverpoint - Empty LUN first ?

Hi,

Environment:

RecoverPoint (EX) Gen 5 RPAs, v5.1.4

Production Site: VNX 5800 + UnityXT 480

DR Site: VNX 5800 + UnityXT 680

Production LUN Size (10 TB)

This is a question about what order I should setup a new CG for RecoverPoint Replication.

Option 1:

Create new production LUN and DR target LUN

Create new RecoverPoint Consistency Group, enable, and wait for Init to complete

Note: With compression and deduplication turned on, it is taking a very long time to Init. Since the LUN is empty, shouldn't the Init be very fast ??

Once Init is complete, then start moving VM's onto the LUN (datastore)

Option 2:

Create new production LUN and DR target LUN

Storage VMotion VMs onto the new LUN (datastore)

Create new Consistency Group for the new production LUN and enable replication

What is the preferred method ? It seems that option 1 is taking a very long time to "seed" the empty LUN, and then it will take a long time again once I start moving data onto the LUN. So I think the answer is option 2.

Thoughts ?

Cheers, Jack...
