Renamed the database to .git/annex/keysdb; the old .git/annex/keys gets deleted during the upgrade. It is possible that an old git-annex process is running during the upgrade. If so, it will be able to continue using the old keys db until the upgrade is complete, and then will presumably fail in some ugly way. Or perhaps the upgrade will be unable to delete the open files on some systems, and so fail with an ugly error message. It's also possible for multiple processes to be running the upgrade concurrently. That should be fine; they will both write the same information into the keys db. Other databases still need to be upgraded.
