Several years ago, before the CMD_HIDE functionality even existed, I used
this basic process to move my PTS DB from AFS 3.2 running on sun4_mach
systems to AFS 3.3a running on SunOS 4.  It worked fairly well, except
that at least at that time prclient couldn't handle creating the magic
foreign cell groups and foreign users used by cross-realm support. 

If you're going to try it, make a copy of your pts database first, and
then compare the output of db_verify -rebuild on the new database with the
old one.


When are you getting this error?  Are you seeing any output from the
ptserver to stdout/stderr?
