Given that FreeBSD 4.10 is so old -- 4.10-RELEASE was around 9 years ago
-- then I'd be concerned about the hardware it's running on. Not just
because of Moore's Law, but simply because components that old are
probably past the end of their expected lifetimes. Certainly for hard
drives -- the churn involved in upgrading the system can quite easily
trigger drive failure.
If I were you, I'd start with a fresh install of FreeBSD 10.3-RELEASE on
at least a new hard drive, but preferably an entirely new server. Then
port over all your local settings and software load. This also has the
very useful property that your old system can be left running while you
do the build, and still be available afterwards if you need to revert
back to it.
If you can't afford new components or new hardware, whatever you do,
don't try and do an in-place upgrade: the partitioning layout needed has
changed quite a lot in the past decade, and you'll find that modern
FreeBSD needs much more space in the root partition than 4.10 did.
You'll end up with a full filesystem and missing important files. In
this situation, you would be better off wiping the system and doing a
reinstall from scratch.
