Migrating DFS

Hi,

I wasnt sure whether this should go in the AD group or here but will try
here first.

We'll be performing DC migration from Win Server 2003 (holding AD,DNS, DHCP)
to Server 2008 in the coming months. I've been given some good advice already
on how to do this from other members here. However, our DC also has DFS.

I'm wondering what the procedure would be to migrate DFS to our new DC too.
Would it be done before we migrate AD, DNS e.t.c. or after? Also, would it be
better to replicate the data accross or use the FSMT?

Any advice/pointers would be great.

Many thanks.
