We migrated to on-prem GitLab running on k8s via the official Helm chart a year ago. We have ~50 users and so far have only had downtime when they required us to migrate from PostgreSQL 9.6 to 11 with the release of GitLab 13, and that was planned. We upgrade multiple times a month to stay up-to-date with the latest patches, and it's painless. I don't regret it.
