Error re ""SY0CTL.SOA cannot be opened"" during 4.40 Parallel Migration - Sage's response to this is to 1) make sure no one is in MAS and no pvxwin32 running, and 2) run from the Wkstation instead.
I just found that if you map a drive on the server at the same point it's mapped on the wkstation, you can get past this error. This was my last ditch effort before giving up for the night and having to call the poor client to come in and reboot a wkstation for me AGAIN. HALLELUJAH!
