ZHA move to Z2M

some post people claim some issues of pairing, devices reconection and better signal handling did improve moving to Z2M.

I think that you would see a much bigger difference if you follow → Guide for Zigbee interference avoidance and network range/coverage optimization.

As mentioned there also maybe consider buying a CC2652P based Zigbee Coordinator with external antenna, like example the “Sonoff ZBDongle-P”, see → https://community.home-assistant.io/t/iteads-sonoff-zigbee-3-0-usb-dongle-plus-model-zbdongle-p-based-on-texas-instruments-cc2652p-20dbm-radio-soc-mcu/340705

That being said, my understanding is that pairing happens between devices and the coordinator, so moving from ZHA to Z2M shouldn’t impose re-pairing.

I do not believe that Zigbee2MQTT has a build-in feature/function to keep an already formed Zigbee network that existng Zigbee Coordinator?

If not then you would at the very least have to manually enter the Network Key and PAN ID that you where using before into the Zigbee2MQTT configuration.

That would be reverse of steps here → https://skyconnect.home-assistant.io/migrate-zigbee-zha/
