I think what I'll need to do is to make a 12.3-R instance and then compare. When the source instance was installed, it was FreeBSD 12.0-RELEASE-p3 GENERIC. If the comparison doesn't exactly match, I could install I guess that 12.0 version instance, and then upgrade the OS to where it is now.. It's not important that it's not the most direct way of doing it, but it's *very* important that the destination can be restored-from. --
