C-7 to C-8 migration left all zigbee devices inoperable

Very similar to my experience last week documented here.

MIgrated to C-8 Pro but no Zigbee

Just did a migration to a C-8 Pro. Everything seemed to go smoothly however none of my Zigbee devices are responding. I see messages showing up in Zigbee Devices, but I'm unable to control them. I did follow the official instructions. I would have thought that once the Hub was receiving messages from a given device that it should work as it has a route established. It's been about two hours with a few reboots and rebuilds thrown in. I've got about 40 Zigbee devices and I really don't want to…

It's no consolation, but mine finally did convert successfully on the 4th attempt.
