I'm sorry, I read all of that stuff before, and I simply don't
come to the same conclusion.
Note that they say things like, "... significantly more expensive and
difficult compared with IPv6's site renumbering ...", and "IPv6's eased
It's _easier_. That's what I (and many others) have said; they've
given you some new tools to deal with renumbering. That is cool.
But NOWHERE does it say that if you plug into a new upstream
provider, IPv6 does all of the work for you ... only you are saying
that. There are very clearly some other things that need to be done
as part of a renumbering (one example: changing DNS around).

I'm sorry, again, this doesn't follow. I don't see how having two
simultaneous addresses and switching over to using the new set
gradually (presuming both are externally visible for some time)
really has anything to do with NAT! And note that they said, "more
convenient renumbering" - it doesn't say, "convenient renumbering".

They already understand this; it's you who is refusing to listen.
