One of the things I did as a precursor to starting to rewrite this program was to review each of the tables that we would need to touch to come up with what the existing ranges are for all of the key fields (there are sometimes more than just the ID field) to find a "safe" range.

There are several cases of where the databases are the same up to a point, but then they diverge. In cases where there is any discrepancy, I'm taking the safe route to come up with a range of id's (for all the key fields) that new records could be imported with. This will be true if you're going cavedude -> PEQ or PEQ -> cavedude. It looks like there is going to be at least one case where we're going to have to alter the database structure (by expanding a field) as the existing ranges are already using all the available space.

Part of what I'll publish when I get the program running is that analysis. That way if I missed something, I'll have lots of folks helping me troubleshoot it. =)
