+#### Migrating to CSI drivers from in-tree plugins
+
+{{< feature-state for_k8s_version="v1.14" state="alpha" >}}
+
+The CSI Migration feature, when enabled, directs operations against existing in-tree
+plugins to corresponding CSI plugins (which are expected to be installed and configured). 
+The feature implements the necessary translation logic and shims to re-route the 
+operations in a seamless fashion. As a result, operators do not have to make any 
+configuration changes to existing Storage Classes, PVs or PVCs (referring to 
+in-tree plugins) when transitioning to a CSI driver that supersedes an in-tree plugin.
+
+In the alpha state, the operations and features that are supported include 
+provisioning/delete, attach/detach and mount/unmount of volumes with `volumeMode` set to `filesystem`
+
+In-tree plugins that support CSI Migration and have a corresponding CSI driver implemented 
+are listed in the "Types of Volumes" section above.
