### RBD CSI Snapshot Incompatibility

CSI snapshot is moved from Alpha to Beta and is not backward compatible. The snapshots
|

created with the Alpha version must be deleted before the upgrade.

Check if we have any `v1alpha1` CRD created in our kubernetes cluster, If there
|

is no `v1alpha1` CRD created you can skip this step.
