The db change is here: https://pagure.io/fm-orchestrator/pull-request/686#_1,18 Two new added columns. The MBS (like many of our other apps) uses `alembic` to manage db migrations. The plan to upgrade involves using this playbook, which will use `mbs-upgradedb` (a small wrapper around alembic). https://infrastructure.fedoraproject.org/cgit/ansible.git/tree/playbooks/manual/upgrade/mbs.yml#n102 If it fails, I'll back it out with `alembic downgrade -1`. If *that* fails, having the additional columns shouldn't hurt anything, so we can downgrade the software but keep the advanced schema until we figure out how to resolve that (likely manual sql statements, but it shouldn't come to that[1]). -Ralph [1] - He says on a Friday afternoon, he says. _______________________________________________ infrastructure mailing list -- infrastructure@lists.fedoraproject.org To unsubscribe send an email to infrastructure-le...@lists.fedoraproject.org
