Upgrading a basic public IP address to Standard SKU for Azure Express Route Virtual Network Gateway

hi,

There is a well known announcement from MS that the public IP basic sku is going to be retired in end Sep 2025.

I have a Express Route Virtual Network Gateway with basic public IP.

The Express Route Virtual Network Gateway has "Standard" SKU, which is a non-Az enabled Gateway SKU.

 

I read the some of the guides in MS, but there is some conflicting information on the migration.

 

(1) In

https://learn.microsoft.com/en-us/azure/virtual-network/ip-services/public-ip-basic-upgrade-guidance

 

It says "New ExpressRoute Gateway is required. Follow the ExpressRoute Gateway migration guidance for upgrading from Basic to Standard SKU."

 

(2) Then in

https://learn.microsoft.com/en-us/azure/expressroute/gateway-migration

 

The guided gateway migration experience supports:

Non-Az-enabled SKU on Basic IP to Non-az enabled SKU on Standard IP.

Non-Az-enabled SKU on Basic IP to Az-enabled SKU on Standard IP.

Non-Az-enabled SKU on Standard IP to Az-enabled SKU on Standard IP.

 

Notice that the first point say that for non-Az-enabled SKU, we can just upgrade the public IP from basic to standard sku.

 

So, i am not sure if

(1) a new gateway is required

or

(2) we just press the link to upgrade basic IP to standard IP ?

 

I don't have a spare lab environment to test this for Express Route, so it can be very dangerous in production to do this action without any understanding or fall back plans.

 

Please help.

    I haven't done this specific upgrade yet, but I see what you're saying.

     

    It will build a new gateway and migrate it automatically.  You don't need to manually create any resources.  All of the work should be in the "Gateway SKU Migration" section of the express route gateway settings menu.  In the "Prepare" phase, that's when Azure should build everything.

     

    I'm fairly confident, but I've upgraded the SKU of a express route gateway before.  It looks like a similar process where you might have to wait 45 minutes as Azure spins up new resources, tests, and migrates the traffic.
