Can I upgrade a single server in my farm, from Xpe FR3 to MFPS 3.0? I do realize that this will then become the DC for the farm. Will this make changes to my SQL datastore as well? Can MF FR3 and MFPS 3.0 co-exist in a farm? I have 60 servers (WIN2K SP4) in a single farm with multiple zones. I do not want to move all of them at once....that is a large undertaking of upgrading.
