Migrate from c5 to c8

If you have the Z-Wave.me UZB dongle then that should be a supported Hub Protect migration option as per Hub Protect | Hubitat Documentation

I'm not sure why that's a different scenario ("Hub Protect" migration) than the one mentioned on How to Migrate to a New Hub | Hubitat Documentation which only specifies C7 migration .....

I did suggest that all these different combinations could be better clarified by Hubitat previously because they are catching a lot of people out.

A simple table of "models / radios / etc" with "supported free / supported Hub Protect / not tested but should work / won't work / etc" would be very useful IMHO.
