 Azure-wide Cloud Services-based infrastructure is deprecating. As a result, the Virtual WAN team has been working on upgrading virtual routers from their current Cloud Services infrastructure to Virtual Machine Scale Sets based deployments. This will enable the virtual hub router to now be availability zone aware. If you navigate to your Virtual WAN hub resource and see this message and button, then you can upgrade your router to the latest version by clicking on the button. If you would like to take advantage of new Virtual WAN features, such as [BGP peering with the hub](create-bgp-peering-hub-portal.md), you'll have to update your virtual hub router via Azure Portal. If the button is not visible, please open a support case.
