The docs say "To trigger auto-creation of the ClusterGroupUpgrade CR, remove the ztp-done label from the cluster and delete the empty ClusterGroupUpgrade CR that was previously created in the ztp-install namespace."

It seems that the order is important. If you delete the "ztp-done" label, and then delete the CGU, the operator will reconcile and create a new CGU.

However, if you delete the CGU, and then the "ztp-done" label, nothing happens, a new CGU is not created.

This is because the operator only watches for CGU deletions to trigger a reconcile. It does not watch the ManagedCluster for updates. So if you delete the CGU, a reconcile happens (with no action, since the cluster has the "ztp-done" label), but when "ztp-done" is removed from the ManagedCluster, no reconcile happens.

Manually deleting the controllermanager pod for ManagedClusterForCgu causes the reconcile to happen, and a new CGU to be created.
