Rolling an image back, or restoring a backup a newer release made, ran older code against a schema it does not know and failed later, far from the cause. Boot now refuses a database that records migrations this build does not ship, and the restore check refuses such a backup while the current database is still in place. A restore also keeps the database it replaces as data/pre-restore-<time>.db.
