I know I changed the functional level of the domain to 2003 before. I just confirmed it.
In the SBS Migration document from Microsoft, you don’t have to raise the functional level of the domain if you still have a Windows 2000 domain controller..but with SBS, could you?

Microsoft talks about it here:
This doesn’t stop the migration at all and we can look at it further later if need be.
