Procedures for Upgrading Aviatrix Controller and Gateways

This section outlines the general Controller and gateway upgrade instructions.

General Controller and Gateways Upgrade Guidance

This section provides general instructions for upgrading the Controller and Gateways.

  • Upgrade the Controller before upgrading the Gateways:

    • It is important to upgrade the Controller first, ensuring it is at the desired release version.

    • Once the Controller is successfully upgraded, proceed to upgrade the Gateways.

  • Upgrade from the current version to the latest release version within the current release:

    • Verify that the latest release version is available for your current release.

    • Consult the documentation specific to your current release version for detailed upgrade instructions.

    • Follow the provided steps to upgrade both the Controller and Gateways to the latest release version.

  • Upgrade from the current release (e.g., version N) to a higher release (N+1 release):

    • Note that neither the Controller nor the Gateways support multi-hop upgrades.

    • Upgrade sequentially from one adjacent version to another.

    • Determine the higher release version (N+1) to which you wish to upgrade.

  • Upgrade HA (High Availability) gateways first, then upgrade primary gateways:

    • To ensure proper continuity and system availability, it is recommended to upgrade HA gateways before upgrading primary gateways. This sequence minimizes any potential disruptions during the upgrade process.

It is recommended to schedule upgrades during a maintenance window when short periods of traffic disruption can be tolerated. In HA setups, the disruption should be minimal.
