feature gate is enabled, user should not upgrade to Kubernetes v1.22. vSphere CSI Driver does not support Kubernetes v1.22 yet because it uses v1beta1 CRD APIs. Support for v1.22 will be added at a later release. Check the following document for supported Kubernetes releases for a given [vSphere CSI Driver version](https://vsphere-csi-driver.sigs.k8s.io/compatiblity_matrix.html#compatibility-matrix-for-vsphere-csi-driver).

- Set CSIMigrationvSphere feature gates to beta.
  Users should enable CSIMigration + CSIMigrationvSphere features and install the vSphere CSI Driver (https://github.com/kubernetes-sigs/vsphere-csi-driver) to move workload from the in-tree vSphere plugin "kubernetes.io/vsphere-volume" to vSphere CSI Driver.

Before upgrading to 1.12, ensure the `driver-registrar` CSI sidecar container for your CSI driver is configured to handle plugin registration (set the `--kubel...
