AKS node pools should match Kubernetes control plane version.


AKS supports multiple node pools. In a multi-node pool configuration, it is possible that the control plane and node pools could be running a different version of Kubernetes.

Different versions of Kubernetes between the control plane and node pools is intended as a short term option to allow rolling upgrades. For general operation, the control plane and node pool Kubernetes versions should match.


Consider upgrading node pools to match AKS control plan version.
