We received an email from Microsoft Azure requesting us to update our Basic SKU VPN Gateway configurations before 30 June 2026.

Hello @Marimuthu G ,

Thank you for reaching out to Microsoft Q&A.

Completely understand the concern about keeping the same Public IP for your web server to avoid disrupting your internal sites.

Answer for your questions:
1.Yes, it’s possible to upgrade from Basic to Standard SKU while retaining the same static Public IP address.

2.The safest approach is usually through the Azure Portal for visibility.

3.No, do not upgrade the Public IP SKU first

Navigate to VPN Gateway → Settings → Configuration and select Delete Basic Public IP Reference. If all operations are showing a Succeeded status and you see the details below in your VPN Gateway configuration, you can proceed with deleting the Basic Public IP reference. (Zero Downtime)

If the operation completes successfully, no further action is required from your side. The IP address will be automatically upgraded to the Standard SKU, and you will see the following message.

If the Delete Basic Public IP Reference operation fails with an error, please check the private message and share the requested details there. Once we receive the information, we will connect with you and walk you through the next steps in the process.
