Upgrading FreeBSD to a new minor version is relatively simple. Here are the commands that will get you there: [upgrading from 10.1-p16]
[steve@blackbox:/var/empty]%uname -a
FreeBSD blackbox.cello.com 10.1-RELEASE-p16 FreeBSD 10.1-RELEASE-p16 #0: Tue Jul 17 05:25:45 UTC 2015 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64
sudo freebsd-update upgrade -r 10.2-RELEASE
sudo freebsd-update install
sudo reboot now
sudo freebsd-update install
sudo reboot now
sudo pkg upgrade
I experienced a couple issues along the way, but they were easily correctable. During the upgrade (first command) the process hung while attempting to download the software it needs. I completely lost my connection so I logged back in and ran it again with no issues. Then during the second “freebsd-update install” the same thing happened. Again, log back in and run it again. No issues. Finally, while running the last command to upgrade the packages on the system I ran into one package it would not upgrade. Running “pkg upgrade” twice seemed to ignore the problem.
