 #### Clusterctl Changes
 
-Today, clusterctl move operates by tracking objectreferences within the same namespace, since we are now proposing to use cluster-scoped resources, we will need to add requisite support to clusterctl's object graph to track cluster-scoped resources that are used by the source cluster, and ensure they are moved. We will naively not delete cluster-scoped resources during a move, as they maybe referenced across namespaces. If a cluster uses a `Secret` for account credentials, the OwnerReference will get set by the controller and the `Secret` will be moved to the target cluster. Any `VSphereClusterIdentity` that's required by the resources being moved, will need to be manually created on the target cluster prior to the move operation.
