Upgrade Gateways in Groups

The gateway group upgrade feature optimizes the gateway upgrade process by allowing you to categorize and manage gateway upgrades more efficiently. It enables the predefined grouping of gateways based on Cloud, Account, Region, Gateway type, Current image version, and Kernel version. By assigning the priority order of the gateway groups, the gateway group upgrade can be operated in a sequence determined by the priority levels, which can minimize the potential disruption during the gateway upgrade.

From CoPilot > Administration > Upgrade > Upgrade Plan, you can access the gateway group upgrade feature.

Subgroup Division

Upon creating the gate groups, each gateway upgrade group is automatically subdivided into two subgroups:

  • HA Group (High Availability Group) This subgroup includes gateway instances that are part of the High Availability setup. These instances are critical for ensuring uninterrupted network services during the upgrade process.

  • Primary Group This subgroup consists of primary gateway instances, which handle the regular traffic and operations within the network.
