VPN gateway versions are constantly evolving and iterating. VPN gateways of the latest version support more features, provide optimized compatibility with third-party devices, and resolve some issues that occur in VPN gateways of earlier versions. If you use a VPN gateway of an earlier version, risks may occur. We recommend that you upgrade your VPN gateway to the latest version to enjoy more features and more stable network performance.
In this example, a VPN gateway that is associated with only SSL-VPN connections is used. For more information about how to upgrade a VPN gateway that is associated with IPsec-VPN connections, see Upgrade a VPN gateway.
Availability of upgrade
You can check whether your VPN gateway is of the latest version by viewing the Upgrade button on the details page of the VPN gateway in the VPN Gateway console.
If your VPN gateway is already upgraded to the latest version, the Upgrade button is dimmed. If you move the pointer over the Upgrade button, the console prompts that the VPN gateway is already upgraded to the latest version.
By default, newly created VPN gateways are of the latest version.
If the Upgrade button is not dimmed, you can click it to upgrade the VPN gateway.
