Well it occurred to me that the xfs_db version command has a help
screen that lists all of the things that it knows how to upgrade.
So, it should be easy enough to detect whether or not it makes sense to
test an upgrade path.  Thanks for the suggestion, sorry I was rambling
about this being harder a few days ago... :/
