Setting up DFS

I have DFS running on a Windows 2003 DC that will soon be decommissioned when I bring up a new Windows 2008 R2 DC.  Should I install DFS on the new DC?  Is it best to use this role on a DC?  Since we don't have replication on this running how do you propose I set it up and have all the existing referral's come over?

Microsoft never recommends using servers with AD security roles on them for anything other then AD security.  DFS will work on application servers.  Since you don't have a replica set up and you're using it for the namespace (I'm presuming??), I would install this on a different server and set it up as a replica.

1 install dfs + dfs replication on 2008 box
2 make sure you have dfs replication enabled on 2003 box
3 add 2008 box to 2003  box dfs as member (do not enable any referals to it yet)
4 overnight run replication from  2003 to 2008
5 swich on referrals for 2008 - and set them up as preferred
6 when sure that it is working disable referals for 2003 box (+switch off replication) but do not delete shares yet (there might be some lingering clients without updated dfs referals)
7 when sure that all clients are using 2008 box disable 2003

OK - when I go through this I believe it prompts to create a namespace but we already have one.  How should I proceed?

you can add server to dfs namespace

To add a namespace server to a domain-based namespace
Click Start, point to Administrative Tools, and then click DFS Management.

In the console tree, under the Namespaces node, right-click a domain-based namespace, and then click Add Namespace Server.

Enter the path to another server, or click Browse to locate a server.
