Comment 2 Wei Duan 2020-09-27 12:46:00 UTC 
1. Set up cluster with 4.3.35
2. Install crd volumesnapshot*.snapshot.storage.k8s.io with v1alpha1 version
3. Before upgrade, check the cluster version info with 
    - lastTransitionTime: "2020-09-27T11:00:02Z"
      message: 'Cluster operator storage cannot be upgraded: Unable to update cluster as v1alpha1 version of volumesnapshotcontents.snapshot.storage.k8s.io, volumesnapshots.snapshot.storage.k8s.io, volumesnapshotclasses.snapshot.storage.k8s.iois detected. Remove these CRDs to allow the upgrade to proceed.'
