Choosing agent update settings

1. In an agent group’s Settings tab, go to the Version section.
2. In Version, choose the version of the agent to apply to this agent group.
3. Enable the option Allow downgrading to older version to allow updates to lower versions of the agent.
   This option is particularly useful if you are experiencing a problem with a version of the agent. It allows you to revert to an earlier version with which the problem does not occur.
4. Disable the Automatically apply software updates option so that agent handlers do not apply updates when deploying to the agent pool again. In this case, only configuration or security policy changes are deployed if they are compatible with the current agent version.

For further information, see Updating agents, for example, to find out how the agents update if you have disabled the second option.
