Console: Admin › Substrate › Upgrades.

Part of the page Shows Guide

The same from the CLI:

Terminal window
stratumctl admin upgrade status          # what runs, and the upgrade in progress
stratumctl admin upgrade available       # newer releases
stratumctl admin upgrade plan 0.3.0
stratumctl admin upgrade history

A cluster upgrades one node at a time: see Upgrade a cluster.

While an upgrade runs, readiness carries UpgradeInProgress, and changes through the API are refused from its backup step until it ends.
