set up replacement loxberry and get zigbee2mqtt to reconnect

[duncan]

Hi,
sorry for the english

i have a loxberry and want to set up a new replacement one - if i set up a new one with the same network name, same radio channel and paste in the list of devices, save and apply, none of my zigbee devices seem to reconnect to the replacement machine

is there any other settings needed so the new loxberry appears to be the old one and all the devices dont need to be manually rejoined?
