 An `rbd` volume allows a

+#### RBD CSI migration {#rbd-csi-migration}
+
+{{< feature-state for_k8s_version="v1.23" state="alpha" >}}
+
+The `CSIMigration` feature for `RBD`, when enabled, redirects all plugin
+operations from the existing in-tree plugin to the `rbd.csi.ceph.com` {{<
+glossary_tooltip text="CSI" term_id="csi" >}} driver. In order to use this
+feature, the
+[Ceph CSI driver](https://github.com/ceph/ceph-csi)
+must be installed on the cluster and the `CSIMigration` and `CSIMigrationRBD`
+[feature gates](/docs/reference/command-line-tools-reference/feature-gates/)
+must be enabled.
+
+{{< note >}}
+
+As a Kubernetes cluster operator that administers storage, here are the
+prerequisites that you must complete before you attempt migration to the
+RBD CSI driver:
+
+* You must install the Ceph CSI driver (`rbd.csi.ceph.com`), v3.5.0 or above,
+  into your Kubernetes cluster.
+* considering the `clusterID` field is a required parameter for CSI driver for
+  its operations, but in-tree StorageClass has `monitors` field as a required
+  parameter, a Kubernetes storage admin has to create a clusterID based on the
+  monitors hash ( ex:`#echo -n
+  '<monitors_string>' | md5sum`) in the CSI config map and keep the monitors
+  under this clusterID configuration.
+* Also, if the value of `adminId` in the in-tree Storageclass is different from
+ `admin`, the `adminSecretName` mentioned in the in-tree Storageclass has to be
+  patched with the base64 value of the `adminId` parameter value, otherwise this
+  step can be skipped. {{< /note >}}
