no customizations on either version, nothing in SY_enhancement or SY_EnhancementModule on either version, renamed Links folder and version error message still pops up. But reinstalling modules (and PU) on the new 2014 SQL version took care of the migration problem. Went back in a tried to migrate another company code and error is not there, so that's good. I think something got messed up in the MAS_System SQL database - even though the version and everything looked ok in the SY_system table.
