Yang Wang commented on FLINK-26811:
-----------------------------------
Mabe we also need to add a simple statement of version upgrading in the README,
just like
[https://github.com/GoogleCloudPlatform/spark-on-k8s-operator#project-status].
> Document CRD upgrade process

> We need to document how to update the CRD with a newer version. During
> development, we delete the old CRD and create it from scratch. In an
> environment with existing deployments that isn't possible, as deleting the
> CRD would wipe out all existing CRs.
