Our app is migrating to a new namespace in Rancher-managed Kubernetes. Currently, the app uses a PVC that is bound to the old namespace. What is the recommended way to migrate or reuse the existing PVC in the new namespace?

Attach a toolbox or default image to the pvc, kubectl cp the data to the server host, then spin up the new deployment/pvc, set it to 0. Deploy the toolbox pod and attach the new pvc. Then kubectl cp from server host to the new pvc.
