We have a server running SBS 2011 Standard with an eval. license which we had originally planned on purchasing, however, we now have decided we want to use Essentials instead. Will this switch be as simple as popping in the CD and saying "upgrade" or will it require using migration tools to make sure all of our settings are still applied?
We are not using any of the features that would be absent in Essentials, and as far as the Windows Server features, it is our DC, AD server, and file share server. The other third party services we use (e.g. Subversion, license servers, etc.) are all easily reconfigurable if need be.
