swapping AiMesh Main and Node

I have two 68u's setup with AiMesh and it's working fine. They are both physically installed/mounted in a way that it's a little difficult to take out and remount.

I've been experiencing trouble with my cable line and want to test out the cable line on another outlet meaning I need to move my cable modem to another room. The new cable modem location would be near the router node.

Question: Is there a quick way to swap main and nodes? or do I need to reset everything and setup...
