Moving from Conbee 2 Deconz to Sonoff ZB Dongle E and Zigbee2MQTT

I know there is no migration path unfortunately. I would like to know how to solve those 2 issues I am having:

(A) Historical data: Entities names are not equal. I am not aware how I can name them exactly the same.

Conbee environment and one sensor device: sensor.temperature_20; sensor.humidity_19; sensor.pressure_21

Now with Zigbee2MQTT: sensor.kitchen_temp_temperature; sensor.kitchen_temp_humidity; sensor.kitchen_temp_pressure

How can I name them equal? If not is there any other chance like renaming UUIDs in the database to get back my historical data?

(B) Is there any chance to migrate a connection from deconz to zigbee2mqtt w/o accessing the device? It is build into a wall and I would need to open it. Don’t ask me why this happened :smiley:
