title: How to enable Calico network policy on the existing AKS cluster
body: <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>
