I followed a very well written guide on how to migrate from SBS 2003 to Server 2008 w/ Exchange 2010. Every step went well until I got to the point of removing Exchange from SBS. When I go into the Add/Remove Programs and select Change/Remove for Windows Small Business Server 2003, I get an immediate pop-up window stating:
"You are attempting to install a version that is earlier than the current version. You can only upgrade to a newer version. Otherwise, complete a new installation of the previous version"
I have done some searches but come up empty. Can anyone give me a suggestion as to how to proceed?
