Thanks for the reply. After some experimentation, I'd concluded that must be true. It is a shame, though. If I started over with the original SQB files, I would lose too much data for my present purposes, as the virtual mounts had been up for some time. So my only option was to make new complete backups of the old virtual mounts and then restore them again on the new server. This is fairly tedious, and it would be nice if there were an easier way. For your consideration.
