Proper way to "decommission" V3 hub

Seven years and three hubs later, I’ve moved 85 devices and 40 pistons to a new platform and it’s time to unplug my ST V3 hub. I will likely sell it or give it away. That said, is there anything I need to do to dissociate it from my ST account? Can I just do a factory reset or is its MAC address somehow tied to Samsung’s infrastructure and/or my account? TIA for any advice.
