One of my servers is colocated in a place on a different continent - which

case (because the logistics on arranging that are ... interesting) or is
there a relatively safe way to upgrade from RELENG_4 to RELENG_6 remotely?
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.
Ditto. I upgraded my cyrus mail server and kerberos server from 4.x to 6.x
remotely from across the world and didn't have any problems. The main caveat
was to include the compat4.x stuff during the upgrade, and to make sure to be
thorough when rebuilding ports and packages. I was careful to boot 6.x test
kernels on all boxes to make sure all hardware probed, etc, before committing
to the update. I would have felt a lot less comfortable without a serial
console in-hand, though.
