primary domain controlller and exchange 2007

Specs: windows server 2003
we have 2 server: windows server 2003 and windows server 2008 r2. In 2008 we have the exchange 2007. The server 2008 need on 2003 to have operative exchange. We change all the roles to server 2008, however there is something I don't know how to change, this is the primary domain controller, still said that 2003 is, for this reason always needs the 2008 to 2003 to have mail runs. Then, I think is good idea eliminate the 2003 from active directory domain?
Thanks for advance to all for help

The dcpromo command is what you might need for that. Wait for someone else to confirm that because I'm not 100% sure.

After promoting your 2008 server to a domain controller, you need to demote your 2003 server using dcpromo. Make sure all the FSMO roles are transferred to your new server before demoting your 2003 server. You may need to completely unjoin the server from the domain and then rejoin it.


Check this.

Not a good idea to remove the 2003 DC. Microsoft recommends a minimum of two DCs for AD failover.
Both should be running DNS server and have the global catalog

If you have no reason to get rid of the old server, then keep it on as a secondary DC as recommended above. However, if you're running a small network and have a reason to get rid of the old one, electricity costs, cost of maintenance, space, etc. then it's not a major problem to only have one server, especially if every single other resource on your network is on the other server. A DC for authentication isn't going to help you much when all of your files, databases, and email are on the down server. The link below details transferring the FSMO's, including the PDC emulator:
