We currently have two DFS servers (one on each site) running Windows Server 2008 RTM. We would like to replace the LIVE site hardware with a new VM running Windows Server 2008 R2. I understand adding the new member to synchronise with the DFS server on the LIVE site but how about the DR site? Is it possible to synchronise the new DFS member with the DR DFS server without it needing to re-sync all the files over the WAN? If so what is the best way to go about it?
