<p>I want to enable Calico network policy on existing AKS cluster. Is there any way to do that?</p>
<p>I found the following statement on the official Microsoft documentation that, <strong>&quot;You can't enable network policy on an existing AKS cluster. To use Azure Network Policy, you must use the Azure CNI plug-in and define your own virtual network and subnets.&quot;</strong></p>
<p>But I raising this question because what if we need to implement this on the existing production level clusters??</p>
<p>If there is no option then for only this thing we need to do various time consuming operations on that production servers and then we have to enable policy.</p>
<p>Please help me on this.
Thank you.</p>

<p>I'm afraid you can't enable the network policy on the existing AKS cluster. It shows <a href="https://learn.microsoft.com/en-us/azure/aks/use-network-policies#create-an-aks-cluster-and-enable-network-policy" rel="nofollow noreferrer">here</a>:</p>
<blockquote>
<p>The network policy feature can only be enabled when the cluster is
created. You can't enable network policy on an existing AKS cluster.</p>
