FYI, it should now also be easy to migrate (using backup and restore process/metod) as well as reset adapters via TubeZB’s zigpy-cli tools add-on if using Z2M with Home Assistant:
Note! If plan on migrating to a new adapter then best practice is to upgrade firmware on new adapter before migrating.
You of course also need to chang the serial port (as well as the baud rate speed and adapter type if needed) in Zigbee2MQTT configuration file so that it matches the new adapter.
PS: Off-topic; Tip is to use respective CC2652 Flasher or Silabs Flasher from TubesZB add-ons or ZigStar add-ons for upgrading adapter firmware if migrating to a Texas Instruments or Silicon Labs adapter.
