+  > At first I get new PVC uid by command:
+  > `kubectl get pvc my-pvc-0 -o yaml | grep uid`
+  > Then I edit new empty volume, what provisioned by CSI Driver and remove claim - pv binding by removing claimRef section in:
+  > `kubectl edit pv pvc-yyyyyyyyyyyy`
+  > After that new PV change status to "Available" and can be deleted.
+  > Then I edit old PV, what I want to bind with pod via new claim and put PVC uid to claimRef section:
+  > `kubectl edit pv pvc-xxxxxxxxxxx`
