Traefik Mesh stores service mesh routing, traffic splitting, and policy configuration in Kubernetes Custom Resource Definitions, so a schema change between controller versions can affect whether existing custom resources remain valid after a downgrade. The goal is to determine whether upgrading the Traefik Mesh controller and later rolling back leaves previo
