You can use Horizon Console to uninitialize the Cloud Pod Architecture feature.
Uninitializing a pod permanently deletes all global entitlements, federation access groups, and federation access group permissions, and returns the pod to a standalone state. This action cannot be undone.
Prerequisites
You need to uninitialize the Cloud Pod Architecture feature on only one pod in the pod federation. If the pod federation contains multiple pods, you must remove the other pods before you begin the uninitialization process. See Remove a Pod From the Pod Federation in Horizon Console.
