Request for developers who own ConBee or RaspBee (deCONZ based adapters) and are depending on zigpy-deconz to consider implementing Zigbee network backup and restore tools to zigpy-deconz (or zigpy-cli) supporting “Open ZigBee Coordinator Backup Format” as already supported by both zigpy-znp and bellows radio libraries:
Note! Please understand that zigpy and the zigpy-deconz radio libraries which ZHA depends on are all free and open-source library with only volunteering developers working on them without pay so remember and you and anyone else are also are more than welcome to code the feature for it (the zigpy developers have so far been more than happy to help and other volenteering developers who are willing to step in to assist with helping to fix bugs or add features).
Again, migration from deCONZ/Phoscon or Zigbee2MQTT is not seamless, as it will only migrate the Zigbee network, (that way you at least do not need to run around and re-pair/re-join all your devices), unfortunately, it does not migrate the entries in Home Assistant so still need to rename those devices and update any automations and scripts that are using the old device names.
Note that if using a ConBee/RaspBee adapter then you first need to upgrade deconz firmware on it.
There is currently no migration path to migrate all settings, devices and entities to Home Assistant ZHA.
Thank you for the information. I tried it but in my case it wasn’t very successfull. Migration from deconz to zha with the conbee II stick did work - but the network was very unstable. I tried to reconfigure the coordinator to the new sonoff stick - but this failed - the entities in ha where correct but they didn’t do anything.
So I reverted to the snapshot and leave it on my deconz for now.
If I get more time - I will try it again
Thanks for all the help.
