VpnGw1 to VpnGw1AZ Migration Help

Question

Hello,

My company is looking to migrate from VpnGw1 to VpnGw1AZ in Azure. We have been reading a few articles starting with https://learn.microsoft.com/en-us/azure/vpn-gateway/gateway-sku-consolidation

On this page it states
Migration period: From September 2025 to September 2026, all existing VPN gateways using VpnGw1-5 SKUs (non-AZ SKUs) could be seamlessly migrated to VpnGw1-5 SKUs (AZ).

Under What actions do I need to take? It states this at the top
We recommend that you don't change your gateway SKU manually in anticipation of SKU migration unless you want to upgrade to a higher gateway SKU. This would apply to us as we want to become zone redundant.

I will also note that there are directions to manually migrate from VpnGw1 to VpnGw1AZ in the Azure portal via the settings > configuration page under the VPN. However the drop down provided to me only lists VpnGw2-3

So unless I am mistaken there is nothing we need to do on our end for the VpnGw1 to VpnGw1AZ migration to take place, we simply need to wait?

Hello @ Austin Klingler,

Thanks for reaching out to Microsoft Q&A.

it looks like you’re diving into the migration from VpnGw1 to VpnGw1AZ. Your understanding is quite on point! Based on the current Azure documentation, there’s indeed no need for immediate action on your part regarding the migration. Starting from September 2025, Azure will handle the transition for existing VPN gateways running VpnGw1-5 non-AZ SKUs to their AZ counterparts, ensuring a seamless experience.

Since you're concerned about the dropdown not showing the VpnGw1AZ option in the Azure portal, it's worth noting that Azure suggests not to change gateway SKUs manually unless you're planning an upgrade. As for your existing setup, you should just wait for the automatic migration, which will occur before September 2026.

To sum it up, here’s what to keep in mind:

• No immediate action is needed from your end for the migration.
• The transition will be automated, and you shouldn't attempt to change the SKU unless necessary.
• For now, you can monitor your configurations and performance, but no manual troubleshooting should be necessary regarding this specific migration.

If you want to be super prepared, you might want to review the migration timeline and potential impacts outlined in Azure's documentation.
