+The `CSIMigration` feature for Cinder is enabled by default in Kubernetes 1.21.
+It redirects all plugin operations from the existing in-tree plugin to the
+`cinder.csi.openstack.org` Container Storage Interface (CSI) Driver.
+[OpenStack Cinder CSI Driver](https://github.com/kubernetes/cloud-provider-openstack/blob/master/docs/cinder-csi-plugin/using-cinder-csi-plugin.md)
+must be installed on the cluster.

+gate. When disabled, in-tree Cinder volume plugin will be responsible for
+all storage related tasks, as it was in the previous Kubernetes releases.
