Transfer config zigbee

Hi. I had home assistant running on a pi 3 but the sd card failed. I have a back up file and a pi 4. Installed home assistant on my pi 4 and used the back up file. everything works fine except all the things on my zigbee network. Im using a sonoff bridge what has tasmota on it. I think all the devices are connected to the bridge but there saying that they are all off line.

Has anyone else had this problem?

Did you use a snapshot ? Or another form of backup ?
