Found that we have DFS on windows server 2003 R2 SP2.  We have AD windows 2008 R2 SP1.   I am thinking of building 2012 R2 servers and install the DFS functions. Can I add the 2012 servers to the namespace servers on the 2003 side?  Should I be able to shutdown the 2003 servers after that and the \\domainname\Group still work when I type it in the windows explorer?

Yes, I believe you can add the 2012 As a DFS target.  Before retiring the 2003 R2 DC you might want to consider transitioning the sysvol from frs to dfs if not done already.

Yes, your conception of this is correct: once replication has happened, you should be able to remove the old replica servers.  Here is an article with some more details and referrals to technet.
