Port upgrade tools are not guaranteed to work perfectly in this
situation. I tried doing an update with portmanager and ended up with
some binaries linked against both libc.so.6 and libc.so.7! Some ports
didn't even compile.

That's why I would recommend doing a clean sweep when updating to
another major version.

It took me about a day and a night to reinstall everything (415 ports),
mostly un-attended. But then I don't use OpenOffice nor java and fvwm2
instead of Gnome/KDE.
