Changing ZHA Zigbee Gateway Sonoff (Tasmota) to Raspbee II (running on Raspi 4B)

Hello Team,

after having a lot of troubles after power lost (Sonoff Tasmota Gateway loses functionality) , I decided to use the Raspbee II. Over the months I have added a lot of Zigbee devices an I don’t want to re-add all these devices again.
Is there a way to change from Sonoff-Bridge to Raspbee II without loosing all my devices, automations,…

Many THX for Your help and best regards
