Upgrading a Gateway
Overview
You can determine whether a VPN gateway can be upgraded by checking whether the upgrade button is available in the Operation column of the VPN gateway.
- If no upgrade button is available, the VPN gateway is of the latest version and does not needs to be upgraded. The version of a newly created VPN gateway is the latest.
- If the upgrade button is available, the VPN gateway is not of the latest version. You are advised to upgrade it.
You can determine whether to perform a rollback when the gateway status is Upgrade to be committed.
Notes and Constraints
If a VPN gateway, EIP, or shared bandwidth is billed in yearly/monthly mode, you can upgrade the VPN gateway or perform a rollback only when the remaining validity period of the VPN gateway, EIP, or shared bandwidth is longer than one day.
Upgrade Impact
- VPN connections will be interrupted for about 10 minutes during the upgrade.
- You cannot perform operations on a VPN gateway or its VPN connections during the upgrade.
Rollback
After the upgrade, you need to check whether services are normal. If there are any exceptions, you can roll back the upgrade. If services are normal, you can commit the upgrade, after which a rollback is not supported.
