Delete a traffic-group

Thanks a lot, for your quickly answer Aayush, but muy question is about the previous step, delete the traffic-group, as I indicated in the added images.

I supose that this step, is less aggresive than make modifications in the device-group and sync policies.

I read the link that you tell me, before write the post. Because I didn't found information about the procedures or impact when modify or remove the traffic-groups. That's my question.

Thanks again.
