Once persistent data is provisioned in a kubernetes cluster there is no easy or automated way to migrate this data to a different storage class. This feature aims to close this gap by providing a high level API that can be used to select PVCs from a given storage class and migrate them to a different storage class regardless of what type of application is using the data and whether that application is active or stopped. The migration may take a long time and should be managed by an operator from start to finish.
