Suppose the old Prefix is BPREFIX and new one EPREFIX, I'll do it like
this:

mv $BPREFIX $EPREFIX
ln -s $EPREFIX $BPREFIX
export PORTAGE_OVERRIDE_EPREFIX=$EPREFIX
emerge portage binutils-config
emerge -e @system
emerge -e @world
sed -i "s,$BPREFIX,$EPREFIX,g" $EPREFIX/startprefix
rm $BPREFIX

not guaranteed, you may come across minor errors, but that's the idea.

Cheers
