Description of problem: Downgrade from 4.11.0-0.nightly-2022-06-15-222801 to 4.10.0-0.nightly-2022-06-08-150219 on Alicloud and IBMCloud, cloud-controller-manager degraded. Version-Release number of selected component (if applicable): 4.11.0-0.nightly-2022-06-15-222801 How reproducible: Always Steps to Reproduce: 1. Set up a cluster on Alicloud or IBMCloud 2. Downgrade cluster from 4.11.0-0.nightly-2022-06-15-222801 to 4.10.0-0.nightly-2022-06-08-150219 $ oc adm upgrade --allow-explicit-upgrade --to-image registry.ci.openshift.org/ocp/release:4.10.0-0.nightly-2022-06-08-150219 --force 3.
