The cleanest way possible really is wipe and reinstall. For your
5.3 systems, I'd strongly recommend you do exactly that -- 5.3 is almost certainly too old to support the newer upgrading mechanisms that have
come into use since it was released and upgrading by cvsup+rebuild will
be exceedingly tedious, as you'll have to take it in a number of steps to
get all the way to 7.0.
For your 6.1 systems, you can update by cvsup+rebuild to RELENG_6_3 in
one step, or via there to RELENG_7_0 in two. (Actually, you can probably
do 6.1->7.0 in one step, but it's not guaranteed to work properly) You
will need to rebuild all your installed software, which is not a trivial
undertaking but once you've got past the first few hurdles rapidly becomes
nothing more than time-consuming.
If your 6.1 system is using a system installed from one of the official
iso images and hasn't been locally rebuilt (upgrading via freebsd-updates
is OK though) then there is a quicker way. See
