Our GKE PersistentVolumes were provisioned with kubernetes.io/gce-pd, but we want to take snapshots of our PVs using VolumeSnapshot. The documentation states that "VolumeSnapshot support is only available for CSI drivers." In order to use VolumeSnapshot we need to change existing PVs to use the pd.csi.storage.gke.io CSI driver.
What is the most efficient way to accomplish this change?
