Okay, all appears to be fine now. I loaded up my old hub and updated the firmware. Then soft rebooted the new hub and did a new migration. Once it was all done, my Zigbee devices were still not working properly, so I rebooted the radio. That seems to have done the trick!
UPDATE: Spoke too soon... Looks like issues again. The devices stopped working again. I looked at the logs and saw an error in a WebCore piston, so I tried to load the WebCore interface. When I click on the link to WebCore in the app list, the page just goes to a loading screen, "Please wait, loading app webCoRE ..."
UPDATE 2: After much finagling, I think I have it all done. Found this post that helped me a bit. Webcore failure after C8 Pro migration - #6 by thebearmay
