Migration C5->C8 pro zwave devices do not actuate

I'm going to sound a bit bitter here perhaps, but, yeah, this is expected, because they didn't catch this early enough and now it's, well, too late and not important enough to address.
Reference Devices "migrated" but none work: C5 to C8-Pro

I wound up moving every device to a new virtual device, to keep the automations/references, deleting the old, creating (pairing) a new, and then moving the virtual to the new.
It's a serious PITA, but at the end, all was well.
I will say, the C8 Pro is quite a bit quicker. But it would be nice if Hubitat had a better migration strategy than "Promise what we know we can't deliver and force them to work around it."
Still, there's nothing better. Just bite the bullet and spend the two hours doing it.
