you should be fine to perform the switch on DC1 - the main
thing is to wait for the domain-level change to replicate prior to changing the
forest functional level (FFL). However, it seems like you only have a single
domain (which is good) - it could be that you're allowed to change to FFL right
away (if you're not allowed, the UI won't let you - it usually checks that all
domains are first switched to 2003 DFS prior to allowing to switch to FFL, but
if there is only one domain, you may be ok). Your member servers couldn't
care less about the DFL/FFL (other than leveraging some of the features
available at this level, such as Domain Local Groups being allowed to be used
for ACLing on your member servers etc.)
Yes, it's a good idea to switch the modes prior to the
Exchange Migration, since Exchange really expects to use Universal Security
Groups in to work (however, in a single-domain, you won't run into many of the
issues that multi-domain environments are challenged with
anyways).

Subject: [ActiveDir] Raise domain/forest function level, any caveats?
Hi,
I have a 2003 AD (upgraded from NT4). I have 3 DCs (2 in main site, one in remote site). DC1 in main site has all FSMO roles.
ALL NT4 BDCS have been removed.
I have 3 NT4 member servers remaining. 1 SQL server, 1 Exchange 5.5, and one fax server.
Is there anything to lookout for before raising domain and forest levels?
I want to begin the 2003 exchange migration process and would rather have the domain/forest level set at native before I run forest and domain prep.
Thanks all
