We are currently trying to upgrade our ProjectWise integration server  from SS2 to SS3 and encountering a problem when we try to run the dmsconv.exe command.  Can someone please provide guidance on how to do this properly?  what we are doing at the moment is from

C:\Program Files\Bentley\ProjectWise\bin, we run

dmsconv –d datasourcename –u SQLserverusername.password –ctr –nomime

But nothing happens.  What user should we put in the SQLserverusername.password field - should this be the same one listed in the dmskrnl.cfg as DBUserName and DBUserPassword or is this a different user altogether?
