How to Update an Existing Virtual WAN Hub to Support the New Microsoft Virtual Router - Alternate Solution

Remove the existing Barracuda NVA, update the routing service of the existing hub, and recreate the Edge Service for Virtual WAN with a recovery token provided by Barracuda Networks Technical Support. This solution can also be used to restore connectivity of your Barracuda SecureEdge Edge Service after the virtual router of the Virtual WAN hub has been upgraded automatically. For more information, see Virtual Router Upgrade for Virtual WAN with Barracuda NVAs.
