Zero interoperability is technically true. However the two protocols can live very happily side by side, NOT interfering with each other. Ricky saying "zero interoperability" is technically true - but not really relevant. As to "no viable upgrade paths" you seem to be a good example of NOT that. Did you replace all your equipment in one great and costly spasm to achieve IPv6 delivery to customers? Getting IPv6 up and running is not a simple thing, but nor is it leaking-blood-from-the ears territory. "It's a forklift upgrade! There are no viable upgrade paths! Zero interoperability!" - this is just Chicken Little stuff.
