Virtual Network gateway - moving to active/active

We currently have a Virtual Network Gateway configured but we want to move to an Active-Active configuration, is there any impact to the current tunnel when enabling Active/Active?83960-image.png

@JohnHust-6865

Once the Azure gateway instances are in active-active configuration, the traffic from your Azure virtual network to your on-premises network will be routed through both tunnels simultaneously, even if your on-premises VPN device may favor one tunnel over the other. Note though the same TCP or UDP flow will always traverse the same tunnel or path, unless a maintenance event happens on one of the instances. Other than that there should not be any change to the current tunnel.
