Need Help ZHA Migration from 1 SMLIGHT SLZB-06M to another SMLIGHT SLZB-06M - Unknown Error

All

Per the title I had an initial SMLIGHT SLZB-06M that just failed and has approx 50 devices (now) connected to it. I have a replacement SMLIGHT SLZB-06M and want to migrate to the new one. However, when I go to migrate, ZHA integration sits for a second or 2 then states ‘Unknown Error Occurred’ and won’t let me continue.

Any ideas on how to get around this and successfully migrate since I don’t want to have to rebuild the entire Zigbee NW again. Again, the original unit is completely failed so won’t even boot etc, therefore cannot do anything with that. Hoping I can still use the new unit and migrate some way.

Thanks in advance

Since I have Home Assistant backups (assume those include the ZHA NW as well) could I just remove the current failed coordinator, add the new and somehow migrate after the fact ? I know it states you can only have 1 controller so not sure how I would migrate after removing the old failed unit.

Thanks

@dmulcahey @TheJulianJES @puddly @Adminiuga kindly tagging in case you can assist directly. Thanks

Answering my own question here to close loop and hopefully help others:

In looking into this further, the Migrate function does NOT work when you do not / cannot have the old/existing Zigbee Coordinator connected.
In my case I cannot connect the current coordinator as its completely failed.
To migrate in cases like this you need to instead click Configure then Reconfigure Radio.
When you get to the Serial path selection, choose Manual (if using the SLZB-06M like I am on POE).
Now choose Manually Enter. Select EZSP (Silicon Labs) as Radio Type then enter the new IP address associated with the NEW / REPLACEMENT coordinator.
Click Submit and after a while you will be presented with options to restore/erase etc. In my case I chose Restore from Automatic Backup.
After a minute or 2 the new/replacement coordinator is in place with the original Zigbee entities / NW attached.

Hope this helps others. Certainly would recommend a doc update on the integration page as I didn’t see this ‘migration’ option documented and this involves different steps than the traditional migration.
