I currently have a default storage class (A) with a reclaimPolicy of "Retain," but I want to switch this to Delete. I've created a second storage class (B) with a reclaimPolicy of Retain. If I have a service that switches to use B instead of A, does that mean they get a whole new volume? Is it possible to reuse the same volume?

Looking for help with a good cutover plan. Any help is appreciated!
