ALL migrations insert major.minor.patch to the database. Migrations are committed to the database, and can be run anytime; they each have check code at the beginning to compare against what's in the database before executing the payload. Migrations won't execute if the version is semantically less or too far ahead from what's in the database. It's worked reasonably well so far.
