Clean and Pristine Upgrade: From SBS2K3 to Server 2008 R2


I am interested in doing a C&P migration and restructuring of our existing AD, which is running on SBS2003.
I've seen the excellent guide on how to upgrade from SBS2003 to Windows Server 2008 R2, but this guide assumes a swing migration.
Is it possible to create a brand new domain, on a brand new server, and transfer the information which I select over to this new domain, but skipping the SBS2003 to Server 2008 upgrade, SBS2003 demotion and creation of trusts between domains?

What I want to do is create the second domain on a separate server, while leaving the SBS2003 server in full production, and gradually move AD objects from the old domain to the new one, including file shares, users, mailboxes, etc.

You can create a new domain on a new server, sure, but the process of transferring information will be much more complicated.  For example, if you have file shares with user permissions attached, those user permissions will need to be deleted and re-created on the new domain.  And you won't be able to move a mailbox to the new domain; you'll have to create a new user account with the same name, create a mailbox, and then use PST files to transfer mail.

Each Active Directory object has a unique identifier (GUID) associated with it, and an object in the new domain, with the same name as an object in the old domain, won't have the same GUID.  Does that help at all?

Question - why aren't you moving to SBS 2011?  It's less expensive.

Migrating SBS (any version) is really not suited for a "take your time" approach.  ADMT can help, but you're just going to create authentication issues for yourself until you get everyone moved.  Why don't you want to preserve AD?

Thank you. I will reconsider my options and look at other alternatives.
Do you have any specifics about how you want to restructure the existing domain?  There may be ways to resolve the root problem without starting a completely new domain.  Feel free to start a new question if it's easier, I suspect that you'll get some good suggestions if you let us know more about the problem.
