The correct fix when upgrading from one major OS version to another

Actually, is there some explicit provision for building a new
/opt from scratch in some other directory, then switching
it in as "the" new /opt (macport binaries).
No, there isn't, sorry. The installation path is hardcoded all over
the installed files.
The thing about such a massive migration is that I'd like to minimize
working downtime. So my current /opt directory is working quite well,
but if I do the correct thing, then I've potentially got a lot of
development downtime while I'm building all the new binaries.
Yes, it is unfortunate.
The only obvious thing that comes to mind is building the ports
on another machine and then copying them over and installing them
as binary packages.
Installing as binary packages would make the MacPorts on the machine
you install onto unaware of their existence and they would collide
with any ports you later want to install on that machine. So I cannot
recommend this procedure.
