Chapter 1. About Red Hat Quay

Red Hat Quay only supports rolling back, or downgrading, to previous z-stream versions, for example, 3.17.2 3.17.1. Rolling back to previous y-stream versions (3.18 3.17) is not supported. This is because Red Hat Quay updates might contain database schema upgrades that are applied when upgrading to a new version of Red Hat Quay. Database schema upgrades are not considered backwards compatible.

Downgrading to previous z-streams is neither recommended nor supported by either Operator based deployments or virtual machine based deployments. Downgrading should only be done in extreme circumstances. The decision to rollback your Red Hat Quay deployment must be made in conjunction with the Red Hat Quay support and development teams.
