Hi all,

Im currently in the process of upgrading to 2012 from 2003. We have a number of DFS roots that were created on a 2003 server that I want to demote, and decommission. At the moment all the root targets are set to this server.

Can I just point the root targets at the new 2012 servers and then remove the link to the old server?

We moved DFS shares from one 2003 server to another by adding the new server to the DFS namespace as a secondary server. We gave it time to replicate, then made the new server the primary server.  Once we confirmed that everything had been copied over to the new server, we removed the old server from DFS namespace.

Although, I have never done that with 2012 server, I don't see why it wouldn't work. I would just run the DFS tools from the 2012 server.

According to Microsoft, migrating File Services role from 2003 to 2012 is supported. Here is a detailed guide for migrating file services.

I hope this helps!

Thanks for reply.

I have now added the 2012 as a target, how do I make this the primary server before removing other server? I don't see the option anywhere on the 2012 tools nor the 2003 tools.

This EE posting might help. The accepted answer details how he moved his DFS to a 2012 server.

You can change the referral ordering to make the 2012 server "first among targets" by going into the properties of each namespace server.  On the 2012 server, make it "first among all targets" and on the older server, make it "last among all targets."  That's all we did in my old job.  We used the term "primary" but it looks like that not how MS refers to it.

You can set one of the file servers as primary using PowerShell, but MS says:  "By default, members are not primary."  So, now I'm not sure that's necessary.
This page has some powershell commands for adding/removing members of a replication group:

Unfortunately, we don't use DFS in my current job so I can't look at that to help you any further.
