<p>At the time of writing, AKS allows setting the network plugin only at the time of cluster creation. So if you have an AKS cluster provisioned with <code>kubenet</code> network plugin and you want to switch to <code>Azure CNI</code>, then currently the only way to achieve that is by recreating the AKS cluster with network plugin set to Azure CNI.</p>
