Using ADMT to migrate from Small Business Server to Windows 2003

I've been tasked with the job of migrating all AD info from a Small Business Server 2003 domain, to a Windows 2003 domain.  First off, since a trust cannot be formed between a SBS domain and a Windows 2003 domain, can the ADMT migration even happen?  I've been reading the ADMT 3.0 guide and it seems a trust between the domains is a requirement.  If I cannot use ADMT, what would be some suggestions on a possible solution?  The source domain on the SBS 2003 does not contain that much information really.  Maybe 120 user accounts if that.  Thanks in advance for any guidance.

No.  ADMT won't work.

Join the new 2003 server as a DC in the SBS domain.
Move all your data to it.
Install DNS on it and allow replication to populate it.
If your using DHCP, then install and configure it, but don't activate the scope.
Make the new server a Global Catalog.
After a night of replication turn off the SBS server and remove it from the network.
Seize all 5 FSMO roles to the new server.
Do a metadata cleanup of AD to remove the old SBS server.
Clean up DNS.
Delete the old SBS server from AD Sites and Services.

You should be done.
DO NOT EVER return the SBS machine to the network without first doing a wipe and load.

Question - why are you doing this like this?  It generally easier and much less expensive to buy the SBS transition pack and migrate away from SBS like that.  Otherwise, you're SBS CALs and license are all essentially wasted and you buy new ones for no good reason.

You still need new CALs with TP.

Perhaps they need a larger infrastructure than SBS can support?

You CAN use ADMT to migrate an SBS server to another server (i have dont it countless times) just need to make sure the 2 Admin passwords are the same and the DNS settings are correct. But netmans way is the best if your going from SBS to full blown Server 2003.

I thought ADMT required Trusts?  SBS can't trust another domain - how did you get that working?

The CALs sold for SBS can only be used with SBS.  UNLESS you "transition" them.  The following PDF from Microsoft would seem to clearly indicate that the (or at worst, a) transition pack will remove this restriction.

"You still need new CALs with TP"

You buy a Transition Pack WITH CALs... at a much lower price than buying the new CALs separately.
