+
+This annotation is automatically added when CSIMigration is turned on for the CSINode object that maps to a node that installs CSIDriver. This annotation shows the in-tree plugin name of the migrated plugin. Its value depends upon the in-tree cloud provider storage type that is used in your cluster.
+
+For example, if we enable the migration where the in-tree cloud provider storage type is `CSIMigrationvSphere`, the CSINodes instance for the node should be updated with:
+`storage.alpha.kubernetes.io/migrated-plugins:  `kubernetes.io/vsphere-volume`
