Binary upgrade from 8.4 to 10.1

[Paul Schmehl]

I am responsible for sysadmin work on two internet-facing servers - 
www.stovebolt.com and mail.stovebolt.com.  Both of these servers are 
production servers, and we have no test or devel servers.  (Small hobby 
website with very little money.)

I want to upgrade from FreeBSD 8.4 RElEASE to FreeBSD 10.1 RELEASE using 
FreeBSD update.

I've done this before, and I don't think I'll run into issues with the 
binary update, but I want to make sure I do everything right and in the 
right order.

Is there a document that describes this process with detailed steps that 
doesn't leave anything out?

I did find this: 
<http://lists.freebsd.org/pipermail/freebsd-stable/2014-November/081088.html>

But I'm wondering if there is an official document that describes every 
step of the process.
