-----------------------------------

[~gyfora] Thanks savepoint restore works. 
[~wangyang0918] How did you switch to the  flink-kubernetes-operator with 
version v1beta1?  because I am getting this error in the 
flink-kubernetes-operator log
"io.fabric8.kubernetes.client.KubernetesClientException: Failure executing: GET 
at: [https://172.21.0.1/apis/flink.apache.org/v1alpha1/flinkdeployments]. 
Message: Not Found."

> 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.
