Anyone have a good tutorial to migrate a W2k domain to W2003?

I have two existing Windows 2000 domain controllers using Active Directory.  I need to migrate my Windows 2000 domain to two new Windows 2003 servers, and retire the existing W2K servers.

In the “old days”, I would just add the two new domain controllers as secondary servers, promote one to the primary server, and obsolete the other two…however I know with the Active Directory setup all these steps are unnecessary.

Anyone have a link to a good tutorial on the best way to do this?  And maybe a good (simplified rough cut) tutorial on the best practices for setting up the “new” W2003 domain?

You prepare the AD, you add the DCs (including DNS).
You move the FSMO roles, you make the new DCs global catalogs.
You demote the old DCs by running dcpromo again (do NOT just shut them down).
