Two Silicon Labs EZSP coordinators

I was forced to change my Home Assistant Yellow. I installed a new CM4 with more memory and moved the data NVMe SSD to the new Home Assistant Yellow. I then restored HA on the basis of a full backup.

When I restarted the new Home Assistant Yellow, the system identified my data disc and I had to confirm the Zigbee channel used previously.

Now I have two Zigbee coordinators in the list of devices and slowly I lose the connection with my other Zigbee devices.


Does anyone have a solution to correct this? Thank you in advance for your comments and help.
