Here how I did it for many remote servers I own and help friends to run.
First install screen from the ports to make your life easier.
After csup to the branch you desire to upgrade to, like RELENG_6_2 or
RELENG_6 to get the latest changes in 6.x branch do these stuff.
#rm -r /usr/obj/*
#mergemaster -iU (-iU added to automatically install files that don't
exist and upgrade those that haven't changed.
