Upgrading AD 2000 to AD 2003

We currently have 1 root domain controller running MSW2000 Server SP4,
1 domain controler (child domain) running MSW2000 Server SP4 and MS Exchange 2000 running on  another MSW2000 Server SP4.  Exchange is currently at SP2.

We have a few questions relating to upgrading AD 2000 to AD 2003.

Has anyone upgraded AD 2000 to AD 2003 without upgrading the server OS to Windows 2003?

Has anyone upgraded MS Exchange 2000 to Exchange 2003 without the server OS to Windows 2003?

If so what potential pitfalls or gottcha's should we be aware of??

Thanks,

In order to upgrade AD to 2003 you must upgrade your DC's OSes to Windows Server 2003.

In order to upgrade Exchange 2000 to Exchange 2003 you must upgrade exchange to 2003 first as Exchange 2003 does not run on Windows 2000 Server.
