You first setup replication connections from your source to target.  Complete your initial replication.  Once you have replicated what you need, you can pause replication.  Shutdown and halt the VNXe that is your target.  Move it to where you want it to be.  Follow emc268724 to re-IP your target platform.  Once you have moved and re-IP'd your target, go into hosts, replication connections and modify and update your current connections.  Once this is complete, replication will continue from the last known good checkpoint.   Good Luck.  Jason
I'm trying to do an initial replication between my 2 VNXe boxes.  The problem is once its complete I need to relocate one of the boxes to a new location.  I have a different subnet at the other location.  Is it possible to change the ip address on the box and maintain the replication?  If not what do you suggest I do for the initial replication?
