Completed a successful migration from C7 to C8.
Couple minor items. Amazon skill needs to be disabled and reconfigured to use the new device.
We also have a mesh. The mesh device names changed requiring me to link the new devices and update the rules that use those devices.
I believe the mesh names are due to the naming convention I use for the hubs.
Other than updating the mesh and rules, I was back online in less than 15 minutes.
Great Job Hubitat!!
