I have upgraded a system from 4.10 to 6.2 via 5.5 half a world away
just using serial console (well and remote power, but that wasn't
needed for the upgrade itself).  I did this via buildworld etc. and it
was actually quite painless, so it can be done.  That said, of cause
there is always the risk that something will make it blow up.

Note that you have to be careful to follow the guidelines to the
letter (see the migration guide which was part of 5.3 or 5.4 docs
AFAIR) for the 4.x -> 5.x part.
