ZHA Devices unavailable after deconz

I am using a conbee 2 stick . I was having zha configured with aqara sensors and some lidl lights. It was working fine. Later I have added deconz addon from store and configured it to add hue and senic switch. Now all my devices in the zha has gone unavailable .

  1. Is it not possible to use both deconz and zha with one conbee 2 stick ?

  2. How can i migrate the devices from zha to deconz without repairing all the devices ?

  3. Which one supports more devices ? Reason why i added deconz was because of hue and senic switch
