There is a Supervisor FAQ that you might take a look at. And, here’s a really old topic from the listserv days where someone lamented about the problems in dealing with multiple security domains.
I believe that if you were to migrate to version XI R2, you’d be happier with how they manage migrations between repositories via BIAR files (although I cannot speak from experience, since we’re on on XI).
And, since this a repository question more than a WebI server question, I’m moving this topic from “WebI Server Administration, Installation, Upgrades” to “Security and User Administration” ==> Supervisor sub-forum.
