**To update a mitigation action**

The following ``update-mitigation-action`` example updates the specified mitigation action named ``AddThingsToQuarantineGroupAction``, changes the thing group name, and sets ``overrideDynamicGroups`` to ``false``. You can verify your changes by using the ``describe-mitigation-action`` command. ::

    aws iot update-mitigation-action \
        --cli-input-json "{ \"actionName\": \"AddThingsToQuarantineGroupAction\", \"actionParams\": { \"addThingsToThingGroupParams\": {\"thingGroupNames\":[\"QuarantineGroup2\"],\"overrideDynamicGroups\": false}}}"

Output::

    {
        "actionArn": "arn:aws:iot:us-west-2:123456789012:mitigationaction/AddThingsToQuarantineGroupAction",
        "actionId": "2fd2726d-98e1-4abf-b10f-09465ccd6bfa"
    }
