title: The address space '10.0.0.0/16' overlaps with '10.0.0.0/16' in virtual network 'ABC'
body: <p>I have created two Virtual Networks in the same region but in a different resource group.<br> But still, I'm getting a warning like <code>The address space '10.0.0.0/16' overlaps with '10.0.0.0/16' in virtual network 'XYZ-VNET'.</code><br> I referred to this link <a href="https://stackoverflow.com/a/41827643/6339597">https://stackoverflow.com/a/41827643/6339597</a> but I still have some doubts because one of the resource groups is in production and another one is in a testing stage. Will it create any issues in the future?</p>
  
  <p>How can I change address space of VNet? Because while deploying MongoDB sharding cluster it didn't ask me about address space for VNet.</p>
