AD transfer from 2003 SBS to 2003 Standard

On last minute notice I have to replace a 2003 SBS server with a 2003 standard because of some SBS limitations. I'm loading the OS on the new box now. The new server is getting the same name so I'm building it on a separate network to get it going and am hoping to swap them out somewhat seamlessly.

I should be able to migrate the Exchange store through Backup Exec to the new server and I'm not too worried about rebuilding the permissions on the share structure, but I'd love to not have to rebuild the AD. There are about 75 users. I didn't build the server originally and the folks the maintained it before I was hired didn't document anything.

Is there a way to take a backup of AD from 2003 SBS and restore it to the 2003 Standard box?

I can't do a full System State transfer because the hardware is different. Is it possible to just pull AD from the System State? I've been in 2003 for a while, but I've never had to do this before. Thanks.

Spend a few bucks on the migration tool here:  www.sbsmigration.com.  It's a god-send for the type of migration you're discussing.

Other than that, you'll need the SBS Transition Pack to move SBS 2K3 to regular 2K3 - http://www.microsoft.com/WindowsServer2003/sbs/techinfo/planning/transition.mspx - but everything I've heard from colleagues tells me that the sbsmigration.com tool is the way to go.

Thanks for the suggestion. I have read some about the swing method as that's what most people seem to recommend. The thing is, all I need is the AD. I don't really want to have to build a TempDC to do this migration. Does anyone know of any software that can be used just to migrate the Active Directory?

Backup Exec will get me everything I need from the SBS box except for the AD...
For an AD-to-AD migration, you can just use the AD Migration Tool (ADMT), a free download from the MS website: http://www.microsoft.com/downloads/details.aspx?FamilyID=6f86937b-533a-466d-a8e8-aff85ad3d212

I haven't used ADMT for an SBS migration before, though, so I don't know if there's anything "funny" about SBS that renders ADMT non-applicable in this scenario.

Thanks again. I think I'm getting somewhere, but the problem I have now is that the new server is the same domain and name as the old server (will be a straight up replacement) so I can't have them on the network together and it looks like ADMT wants to connect directly to the server it's migrating to.

I do have another 2003 R2 server that's on the active network that is not a domain controller, just a stand alone dev box. I didn't want to mess with that server, but I suppose I could use it to help migrate then worry about straightening it out later since it's only used for development.

So I guess my question is this, if I were to enter that 2003 R2 stand alone server into the equation, what would be the easiest way to migrate just AD? I'm not sure I understand the order that would be needed or if ADMT is still the right method. If I were to dcpromo the dev box, what should I make it as to not conflict with the existing SBS box, etc.?

I think option 2 may be the ticket. Will it matter if the swing server is a 2003 SBS server? I just found out there is another decommissioned SBS box that I can do what ever with. I know multiple SBS's on the same network has its limitations, but it seems like if they are different domains that the ADMT should still work, right?

So I'd be putting another SBS with a different domain on the network, run ADMT to migrate to the swing box, then use ADMT to migrate to the new Standard box on the original domain. Sound about right? Thanks!
In theory, that should work.  I'd test the heck out of it in a lab, though, as it's a non-trivial operation any way you slice it.
