 ## Test Plan
 
+[x] I/we understand the owners of the involved components may require updates to
+existing tests to make this code solid enough prior to committing the changes necessary
+to implement this enhancement.
+
+### Prerequisite testing updates
+
+To enable CSI Migration, the stability of CSI driver need to be ensured as a pre-requisite.
+Kubernetes sig-storage team created the CSI driver [e2e test suite](https://github.com/kubernetes/kubernetes/tree/master/test/e2e/storage) framework to
+allow each storage provider to run their driver against these tests to ensure functionality of the driver.
+
+In addition, each storage provider should also have their own testing to ensure feature parity between 
+the in-tree plugin and the corresponding CSI driver. This is done on a per-driver basis.
+
+### Unit tests
