Moving AD from 2003 SBS to Windows Server 2008

I have a Windows 2003 SBS server that I want to replace with a Windows 2008 server.
To move AD off of the 2003 server, I plan to promote the 2008 server, then demote the 2003. This is the process I've been able to find so far:

Step 1: Back up all existing HDs at least 4 times. :-)

Step 2: Follow the instructions here to promote the 2008 server.

Is there anything more that I need to do before demoting the 2003 server?
Have I missed anything in the steps above?

1) Uninstall Exchange 2003 before demoting the SBS 2003 server. If you demote it first, you will not be able to uninstall Exchange, and that will in turn leave some orphaned objects in Active Directory that can cause you problems down the road.

2) Keep in mind that once you demote SBS 2003, it is no longer in legal compliance with the license. This should only be done as the last step before turning off the machine and deleting the entire account from your new Active Directory server. You cannot run it as a member server. You should not do this before moving all line-of-business and other 3rd-party apps elsewhere. Those should all be moved *before* demoting.

You're completely leaving out the steps that remove Exchange and clean out AD.

I would suggest following the steps in the Migrate Windows Small Business Server 2003 to Windows Small Business Server 2008 document instead.  SKIP any steps that you obviously cannot do, but for the most part, follow the directions.
