 * StandardV2 NAT Gateway disrupts outbound connections made with Load balancer outbound rules for IPv6 traffic only. Standard SKU NAT gateway can be used to provide outbound for IPv4 traffic while Load balancer outbound rules is used for IPv6 outbound traffic. If you see disruption to outbound connectivity for IPv6 outbound traffic with Load balancer outbound rules, remove the StandardV2 NAT Gateway from the subnet or virtual network. Use Load balancer outbound rules to provide outbound connectivity for both IPv4 and IPv6 traffic. Or use Standard SKU NAT Gateway to provide outbound connectivity for IPv4 traffic and Load balancer outbound rules for IPv6 traffic.

To return the virtual network or subnet to a successful state, remove StandardV2 NAT Gateway, create and add a virtual machine to the subnet and then reattach the StandardV2 NAT Gateway.

 ### Is my Standard NAT gateway deleted after migration? 
 
-No, migrating to StandardV2 NAT Gateway doesn't delete your existing Standard NAT Gateway or Standard SKU public IP resources. You need to manually delete these resources if they're no longer needed. Don't delete these resources until you fully validate that your workloads are functioning as expected with StandardV2 NAT Gateway and you no longer need the Standard NAT Gateway or Standard SKU public IPs.
