Exchange 5.5 to 2003 migration while in mixed mode NT4.0/2003 domain

I'm a bit confused by Microsoft's documentation when it comes to migrating exchange versions while in a mixed mode domain.  Is it possible to sandwich an exchange migration in the middle of the domain migration…after we have a 2k3 running in mixed mode with NT 4.0 BDCs, but before we’ve raised the domain functional levels?

Right now our strategy is to get the domain in mixed mode via the standard procedure of upgrading a temporary PDC to 2k3.  Then we'll move that machines PDC functionality to the permanent 2k3 machine via dcpromo.  So at this point we'll be in mixed mode, can I go through the "Standard Deployment Method" for 5.5 to 2k3, i.e. link the new win 2k3/exchange 2k3 machine to the existing 5.5 box and start moving mailboxes.

I have all of the documentation for both procedures, just haven't heard or seen any thing about people doing them concurrently.  Honestly, I can't see an alternative method with all of the ancillary services we have running off of the existing exchange server, so any advice would be greatly appreciated.

Hi,

First of all make sure you move all your users from NT domain to W2K3 domain.

We always recommend following the EXDEPLOYMENT TOOLS and ADCTOOLS to avoid the migration issues.

The 1st link under "Set up of new server" has this listed as one of the first steps:

•      Before you upgrade to Exchange Server 2003, make sure that your network and your servers meet the following system-wide requirements:
       •      Domain controllers are running Microsoft Windows 2000 Server Service Pack 3 (SP3) and later, or Microsoft Windows Server 2003.

Doesn't this mean the domain can't be in mixed mode?  Anyone have experience with this?
