Moved the new (buster) hosts to use the trove DB instance, I had to remove a non-longer use column from the
query_revisions table (dbs was replaced by query_database at some point, but it's still left over on the old database).

Left it running there.

@Mdipietro Currently the buster deployment is completely separate from the old one, as they are using different DBs and
redis instances (see T290059).

Part of this is working well. However, I do see an issue:

Sep  6 23:23:05 quarry-dbbackup-01 systemd[1]: quarry-cleanup-mysqldump.service: Failed with result 'exit-code'.
