OCI Kubernetes Engine (OKE) support for rolling back managed nodes to an earlier Kubernetes version

You can now roll back the version of Kubernetes running on managed nodes in a node pool by specifying an earlier available Kubernetes version for the existing node pool, and then replacing the existing managed nodes. The Kubernetes version you specify must be available for the managed node pool and compatible with the version that is running on the control plane nodes. The Kubernetes versions available for a managed node pool can vary by tenancy. For more information, see Rolling Back Managed Nodes to an Earlier Kubernetes Version.
