 ###### Were upgrade and rollback tested? Was the upgrade->downgrade->upgrade path tested?
 
-TODO Upgrade and rollback will be tested when the feature gate will change to beta.
+Tested in Beta:
+
+1. Enable both feature flag and beta API in api-server, create PVC with VAC1, and then modify to VAC2
+2. Turn off the feature flag first, and then try to modify PVC back to VAC1, got error: 
+
+```
+The PersistentVolumeClaim "test-pvc" is invalid: spec.volumeAttributesClassName: Forbidden: update 
+is forbidden when the VolumeAttributesClass feature gate is disabled
+```
+
+The pod and volume are both up and running.
+
+3. Turn off the beta API, this time ``kubectl get vac`` got error:
+```
+Error from server (NotFound): Unable to list "storage.k8s.io/v1beta1, Resource=volumeattributesclasses": 
+the server could not find the requested resource
+```
+
+The pod and volume are both up and running.
+
+4. Turn on both feature flag and beta API in api-server again. ``kubectl get vac`` shows the VACs again.
+
+Change PVC back to VAC1, modify is applied.

 ###### Is the rollout accompanied by any deprecations and/or removals of features, APIs, fields of API types, flags, etc.?
