We have been trying for a long period to resolve issues using Server 2012 DFS servers; and have finally decided to roll back to Server 2008 R2 instead. There are 2 machines in the DFS setup, one of which has been completely wiped (data and OS) and rebuilt. the other machine is a 2012 Server which is currently the master server in the DFS Namespace, which is still in use.
The plan now, is to finish rebuilding the second server with 2008 R2, and use Robocopy to transfer the data across from the life server, share by share, then add the server into the DFS Replication and namespace. Once it has finished replication setup between the two servers, change the new server to be the master, and disable the current primary server in DFS-N and replication.
From here i'm a little unsure of the best step - would i be better completely wiping the second server as well and doing a full data transfer, or is there a way i can still use the data on the current 2012 server by restarting the replication once i have rebuilt it in 2008 R2? As this is a live environment my primary concern is to NOT lose any data (obviously!)
