VMware periodically updates vSphere Advantage and vCenter Cloud Gateway whenever an update is available.

Backing up vCenter Cloud Gateway is not necessary, because it is stateless and can be redeployed if needed.

To view the current version for vCenter Cloud Gateway, log in to https://gw-address:5480/ui and select Help > About.

For vCenter Server, when an update is available, you will see a notification in the VMC Console. When you click Update, VMware will upgrade your vCenter Server.
