Migrating vnet with VPN gateway and ExpressRoute to Virtual WAN

Question

I have an existing vnet with both VPN and ExpressRoute gateways functioning correctly. If I want to import this vnet into Virtual WAN, do I have to recreate the gateways and obtain a new service key for ExpressRoute?

@ares ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you are in the process of migrating to Azure vWAN.

To answer your queries, I shall split it into two,

A. do I have to recreate the gateways

• Yes
• You are required to create new VPN and ExR Gateways in the vWAN's Virtual Hub and add connect the VNET(s) to this vWAN.
• Make sure you remove the Gateways in the VNET, before connecting it to the vWAN.

B. obtain a new service key for ExpressRoute?

• No
• ExR Gateway and ExR Circuits are two different Azure resources.
• Only ExpressRoute Circuits need a Service Key.
• You can simply create a connection between the newly created ExR Gateway (in vWAN) to the existing ExR Gateway i.e. No need to create a new ExR Circuit
• See : Create an ExpressRoute association to Virtual WAN - Azure portal
