- With the release of the CSI 1.0 API, support for CSI drivers using 0.3 and older releases of the CSI API is deprecated, and is planned to be removed in Kubernetes v1.15. CSI drivers should be updated to support the CSI 1.0 API, and deployed in the new kubelet plugin registration directory (`{kubelet_root_dir}/plugins_registry/`) once all nodes in the cluster are at 1.13 or higher ([#71020](https://gith...

  as it requires installation of AzureFile CSI Driver. Users should enable CSIMigration and
  CSIMigrationAzureFile features and install the [AzureFile CSI Driver](https://github.com/kubernetes-sigs/azurefile-csi-driver)
  to avoid disruption to existing Pod and PVC objects at that time. Azure File CSI driver does not support using same persistent

It is only required for drivers...

These extension points can now be abstracted away due to their irrelevance for most users.

### CSI Migration updates

CSI Migration enables the replacement of existing in-tree storage plugins such as `kubernetes.io/gce-pd` or `kubernetes.io/aws-ebs` with a corresponding CSI driver.
If CSI Migration is working properly, Kubernetes end users shouldn’t notice a difference.

  General Support for vSphere 6.7 will end on October 15, 2022. vSphere 6.7 Update 3 is deprecated in Kubernetes v1.24.  Customers are recommended to upgrade vSphere (both ESXi and vCenter) to 7.0u2 or above.  vSphere CSI Driver 2.2.3 and higher supports CSI Migration.
