Major Upgrade Paths

Use these paths when planning multi-version upgrades:

Purpose

The Overview page summarizes gateway health and the recommended upgrade path for your Controller and gateways. Use it to see which gateways are down or on a different software version than the Controller, and to follow the guided upgrade timeline before you start Controller or gateway upgrades.

Elements

Maintenance: Overview
  • Guided Upgrade alert: Reminds you to upgrade incrementally when several versions behind, to upgrade gateways only after the Controller reaches the target version, and to review Release Notes before upgrading.
  • Gateway State and Health: Section showing health and version status by gateway role.
  • Transit Gateway card: Status badge and message when one or more Transit Gateways run a different version than the Controller.
  • Spoke Gateway card: Status badge and message when Spoke Gateways are down or not on the Controller version.
  • Specialty Gateway card: Status badge and message when Specialty Gateways are down or not on the Controller version.
  • External Connections card: Status badge for Site-to-Cloud external connection health.
  • View Down Gateways and External Connections: Button that opens a dialog listing down gateways and external connections.
  • Upgrade Path: Timeline of the recommended upgrade sequence.
  • Current Version: Controller version at the start of the timeline (or Current Controller Version and Current Gateway Versions when gateways run a mixed version).
  • Upgrade Controller to <version> (<upgrade type>): Controller upgrade step on the timeline, showing the source and target version and the upgrade type (Software or Image). Appears once per required Controller upgrade.
  • Go to Controller Upgrade: Button on the active Controller upgrade step when the Controller is the next recommended action.
  • Upgrade All Gateways to <version> (<upgrade type>) or Upgrade Selective Gateways to <version> (<upgrade type>): Gateway upgrade step on the timeline, showing the source and target version(s) and upgrade type. Uses Selective Gateways when only some gateways need upgrading.
  • Go to Gateway Upgrade: Button on the active gateway upgrade step when gateway upgrades are the next recommended action.
  • Target Version: Marker on the timeline for the target version at the end of the current path segment (when shown).
  • <N> intermediate version(s): Italic timeline entry when additional Controller upgrade steps remain after the visible segment.
  • Latest Version: Latest available Controller version in the upgrade catalog.
When the Controller and gateways are already on the latest version, the Upgrade Path pane instead shows a message that you are already on the latest version.
