Hi All,

I would like to setup DFS here to increase my flexibility around file sharing. Currently my files are located on a 2003 server. I want to setup DFS on a server2012 box and migrate the file structure while maintaining security and share names as well as the current unc paths. I know i can use Robocopy to take care of the ACL challenge, but am kinda lost on best approach to migrate to DFS and maintain unc paths.

Can anyone point me on the right direction?

You can copy data from 2003 server to 2012 server with security through Robocopy

In order to keep UNC path same, you need to rename new server with same name as old server

The below approach can be reviewed
copy all data from 2003 server to 2012 server with robocopy
Keep drive letters same on both servers
Export shares registry on 2003 server at below path
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares]

Post completion of data, shutdown the 2003 server and reset its computer account in AD
Join 2012 server to domain with same name and IP as 2003 server
Post reboot import above shares registry key
This should gives you all shares without losing UNC paths

Now you can create DFS root and new name spaces and can set dfs replica etc

What if I do not want to setup the new server with the same IP and same name. I am looking to migrate data from my satellite offices to headquarter and create some sort of replication to a DR site
