Get a stick of flash, build system, install it on the flash and boot 
from it. Try to keep all of your old binaries - I personally don't think 
that all what you have installed will work nowadays. Keeping binaries 
gives you a choice to make a 5.4 jail and put there everything you can't 
install from ports.

Personally I have one computer running X_STABLE or switching to 
X_CURRENT before release. When I see that everything on that machine is 
safe and sound I try to update (after RELEASE of course) least crucial 
servers and so on. By the time I move on to mission critical servers I 
have already found all smelly places. When I was moving from 7.2 to 8.0 
it was just:

# cd /usr/src
# idprio 15 make -j8 buildworld buildkernel && make installkernel 
# cd /usr/ports/misc/compat7x ; make install clean
# shutdown -r now
# cd /usr/src ; yes | make delete-old ; yes | make delete-old-libs
# portupgrade -fr '<date of kernel compile'

This can sound silly to install kernel and world at once but in this 
situation most of my servers are on ZFS, and ZFS won't come up if you 
boot 8.0 kernel over 7.2 userland - you just need to have correct libs 

Sphinx of black quartz judge my vow.
