I would strongly advise you not to attempt doing something like this
remotely over ssh(1). Chances are what will happen is the machine
will crash and end up in an unbootable state.
In order to upgrade a system you really have to have access to the
system console. That means either you have to be right in front of
the machine, or you have to use a serial console either with a console
server or by connecting it via a null-modem cable to a nearby machine.

Not if your job or your company depends on it. Not unless you enjoy pain.

Well, the choice at the moment would seem to be 4.9-RELEASE, 4.10-RC1
or 5.2.1-RELEASE. If you can wait for a few weeks, 4.10-RELEASE will
be available. That is what I'd go for first on a machine being used
as a serious server. However, 5.2.1-RELEASE while still a developer
preview is getting well on the way towards stability. You might need
it if you have hardware unsupported under 4.x.

Under 4.x it's in /stand/sysinstall
Under 5.x it's in /usr/sbin/sysinstall
