==== Required administrator acknowledgment when updating from {product-title} 4.19 to 4.20
In {product-title} 4.17, a previously xref:../release_notes/ocp-4-20-release-notes.adoc#ocp-4-20-removed-kube-apis_release-notes[removed Kubernetes API] was inadvertently reintroduced. It has been removed again in {product-title} 4.20.
Before a cluster can be updated from {product-title} 4.19 to 4.20, a cluster administrator must manually provide acknowledgment. This safeguard helps to prevent update issues that could occur if workloads, tools, or other components still depend on the Kubernetes API that has been removed in {product-title} 4.20.
Administrators must take the following actions before proceeding with the cluster update:
. Evaluate the cluster for the use of APIs that will be removed.
. Migrate the affected manifests, workloads, and API clients to use the supported API version.
. Provide the administrator acknowledgment that all necessary updates have been made.
All {product-title} 4.19 clusters require this administrator acknowledgment before they can be updated to {product-title} 4.20.
For more information, see xref:../updating/preparing_for_updates/updating-cluster-prepare.adoc#kube-api-removals_updating-cluster-prepare[Kubernetes API removals].
