Detach (unimport) a managed cluster safely from the hub

Identify the managed cluster:

oc get managedcluster

If required in your environment, remove dependent placements/policies/apps targeting it (exam often expects you to check “why deletion stuck”).

Delete managed cluster:

oc delete managedcluster cluster-dev

Watch finalizers and cleanup:

oc get managedcluster cluster-dev -o yaml | grep finalizers -n

Why this matters:

Proper lifecycle operations (import/manage/detach) is core EX432/EX480 scope.
