I am in the process of migrating a network from SBS '03 to Server '12 and Exchange '13. The Server '12 box is already online and has had the FSMO roles replicated to it, and I've already migrated all of the mail roles from Exchange '03 to a temporary Exchange '10 box. I am now trying to uninstall Exchange '03.
When I go to Add/Remove Programs and click on Change/Remove for Windows Small Business Server 2003, it brings up the requirements and has two errors:
--This server has a trust relationship with <existing domain>.local.
--Windows Small Business Server 2003 cannot be installed on a domain controller that is not the assigned the operations master roles.
On the SBS '03 Server or on the '12 Server, when I go to Active Directory Domains and Trusts, right click on the domain, go to Properties and then the Trusts tab, there are no outgoing trusts or incoming trusts, so I'm not sure what to remove.
The second error is presumably because I moved the FSMO roles to the '12 Server.
The wording of the Setup Requirements suggests that it's trying to INSTALL SBS '03, not uninstall it. I could transfer the FSMO roles back to the '03 Server temporarily, but I feel like that's not a good idea. Even so, that wouldn't get rid of the trust relationship error.
I realize that I can uninstall Exchange manually, but I'd rather not resort to ripping it out of the SBS '03 box unless absolutely necessary. How should I proceed?
