+#### CSI Migration
+
+{{< feature-state for_k8s_version="v1.14" state="alpha" >}}
+
+The CSI Migration feature for GCE PD, when enabled, shims all plugin operations
+from the existing in-tree plugin to the `pd.csi.storage.gke.io` Container
+Storage Interface (CSI) Driver. In order to use this feature, the [GCE PD CSI
+Driver](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver)
+must be installed on the cluster and the `CSIMigration` and `CSIMigrationGCE`
+Alpha features must be enabled.
