Hi Adam,
The message you are seeing is normal.
What SKU is your current VPN Gateway? This will help me give you more specific advice. The migration procedure that will allow you to upgrade your Public IP to Standard SKU varies depending on your VPN Gateway SKU.
1. If your VPN Gateway SKU is Basic, the migration approach for Basic SKU VPN Gateway has not been published. The current timeline is for it to be published by July 30, 2025. There is no action needed yet.
Screenshot excerpt from documentation below:
2. If your VPN SKU is not Basic, please navigate to your VPN Gateway in the portal, click Settings -- Configuration to see if you have Migrate tab. If you have Migrate tab, please follow instructions in article below:

If Migrate tab is not there, it means the migration functionality hasn't rolled out to the region yet. Please see article below for more detailed information on timelines:
