 For the most consistent upgrade experience, Datadog recommends managing upgrades from one source at a time. Use either Fleet Automation or a configuration management tool. If you run a configuration management tool on an Agent that has already been upgraded using Fleet Automation, the upgrade reverts the Agent to the [`DD_AGENT_MINOR_VERSION`][9]  specified in your configuration. If no `DD_AGENT_MINOR_VERSION` is set, the Agent is upgraded to the latest available version.
