Migrate AD from W2K to W2003 Server

I am running Exchange 2003 on Windows 2000 Server. This Server is also running AD and DNS. I would like to migrate AD and DNS to a new 2003 Server (new - not in production yet). I would like to leave Exchange running on the 2000 server. Can this be done?

Demoting the server with Exchange Installed on it is not supported please see.

I read the artical, I understand that I should not use DCPROMO to demote the current Exchange 2003/2000 server. Does this mean that I should just bite the bullet and backup the exchange server, create a new 2003 server (on my new server), make it the DC, install DNS, wipe out the current Exchange server, join the domain and reinstall exchange?

I ended up using Backup Exec 11d to backup all data from my current exchange server (Exchange 2003 running on W2K server). I also created a second backup on, of the information store,  an external HD.

I created my new AD Server runing DNS (this was a new server), wiped out my exchange server and joined the new domain (Windows 2003/Exchange 2003), installed Backup Exec and restored using redirection - this worked great. It took me a full day but I created my Domain Controller before I brought down the old exchange server. And joined all workstation to the new domain before hand.
