Most Azure-hosted companies are challenged with the basic SKU public IP address and VPN Gateway Migration. This article will give you an update on migrating the VPN Gateway's Basic SKU public IP address to Standard SKU without changing the IP address.
The Current scenario is that you will face several issues if you want to migrate the VPN Gateway's basic SKU public IP address.
- 1 to 2 hours of downtime.
- Download all connection configurations.
- Remove all the Connections belonging to the VPN Gateway.
- Delete the VPN Gateway.
- Recreate the VPN Gateway.
- Share the New public IP address with the customer to change their Firewall.
- Recreate the Connections.
Microsoft has announced a preview feature for the migration without changing the IP and other configurations.
During the public IP address SKU migration process, your Basic SKU public IP address resource is migrated to a Standard SKU public IP address resource. The IP address assigned to your gateway doesn't change.
Note. If your VPN Gateway SKU is VpnGw 1-5, it has been migrated to a VPN Gateway AZ SKU (VpnGw 1-5 AZ).
It will take a maximum of 15 to 20 minutes of downtime.
Step 1. In the Azure Portal, navigate to the VPN Gateway, on the Configuration page, there are two options: Configure and Migrate. Select Migrate.
