{{< note >}}
* Existing PVs created by in-tree volume plugin can still be used in the future without any configuration changes even after the `CSIMigration` is completed and corresponing in-tree volume plugins are deleted.
Existing PVs created by a in-tree volume plugin can still be used in the future without any configuration
changes, even after the migration to CSI is completed for that volume type, and even after you upgrade to a
version of Kubernetes that doesn't have compiled-in support for that kind of storage.
As part of that migration, you - or another cluster administrator - **must** have installed and configured
the appropriate CSI driver for that storage. The core of Kubernetes does not install that software for you.
* New PVs in manifests referring to in-tree volume plugins can still be created, even after the in-tree volume plugins are removed from Kubernetes.
