How do I check which roles are on the 2008 box and which roles are on the 2003 box? and How do I get the roles over to the new box.
Also, I have updated DHCP to reflect only the new server as DNS - Will this automatically change the clients unless they are statics for some reason?
One last thing, I setup the printer service, DHCP server, and DNS Server on the new box - Do I remove these roles from the old box??
Thanks Tigermatt!!! I appreciate all your help you've given me.

If Exchange is on the old DC then it will continue to use that DC until Exchange is removed and the machine demoted. You can transfer the roles without it having an adverse effect on Exchange; the only requirement for Exchange installed on a DC are that the DC is also a Global Catalog (GC) server.
You will need to ensure you have transfer all 5 FSMO roles to the new DC. It must also be a DNS Server and should have replicated your DNS zones automatically through Active Directory.
For client machines to work when the old DC is demoted, they MUST refer to the new DC's IP address as one of their DNS servers. Ensure you have updated this in your DHCP server and on any statically-assigned client machines or member servers. Active Directory resources are located through DNS; if no functioning DNS server is available, domain functions will not work.
