There are two approaches:

1) Back up all your data and config files. List all your installed ports
to a safe location before updating.  Delete all installed ports.  (either just before or just after updating the base system: makes little 
difference.)   Reinstall them all from scratch after doing the update.

2) Manually delete and then reinstall portupgrade and its dependencies
( ruby, ruby18-bdbXX, dbXX -- possibly openssl if you have it installed
from ports )  Once you've deleted the 6.x packages, you should be able
to just:

   # cd /usr/ports/ports-mgmt/portupgrade
   # make install clean

Then use the newly build portupgrade to force upgrade everything.  This
takes a long time and always seems to fall over in the middle, so a good
trick is to say:

   # portupgrade -fa -x ">=2008-7-17"

meaning "upgrade everything except packages installed after the date
of the upgrade."  If it flails in the middle you can fix the problem
and rerun that command without ending up rebuilding everything all
over again.

Option (1) will probably give better results, but it is a log more
intrusive.  (2) works OK, eventually, if you keep plugging at it.

	Cheers,
