#### Portworx CSI migration
{{< feature-state for_k8s_version="v1.23" state="alpha" >}}
The `CSIMigration` feature for Portworx has been added but disabled by default in Kubernetes 1.23 since it's in alpha state.
It redirects all plugin operations from the existing in-tree plugin to the
`pxd.portworx.com` Container Storage Interface (CSI) Driver.
[Portworx CSI Driver](https://docs.portworx.com/portworx-install-with-kubernetes/storage-operations/csi/)
must be installed on the cluster.
To enable the feature, set `CSIMigrationPortworx=true` in kube-controller-manager and kubelet.
