freebsd-update : 6.2-RELEASE to 8.1-RELEASE
Put on sysadmin hat and upgraded some 6.2 freebsd boxes recently. Here are the steps that I used. Please take note that you should have a good backup before attempting this upgrade. You are WARNED!
old6# uname -a
FreeBSD old6.vnet.0rg 6.2-RELEASE FreeBSD 6.2-RELEASE #0: Fri Jan 12 10:40:27 UTC 2007 root@dessler.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386
A rather aged machine without any update. Damn the lazy sysadmin:P
Now grab freebsd-update script from Colin Percival’s realm on people.freebsd.org and extract it. Note that you can’t use the default freebsd-update script in base as it does not have “-r” switch to upgrade your box to other -RELEASE.
old6# fetch http://people.freebsd.org/~cperciva/freebsd-update-upgrade.tgz
old6# tar xvfz freebsd-update-upgrade.tgz
Next, fire up the freebsd-update script to upgrade the system to 8.1-RELEASE. You would be prompted to upgrade your kernel first if you use other kernel than GENERIC or SMP. You need to build and install a 8.1 kernel manually before proceed with freebsd-update install. The upgrade script will also prompt you with bunch of questions on file merge. They are pretty much self-explanatory.
old6# ./freebsd-update.sh upgrade -f freebsd-update.conf -r 8.1-RELEASE

At this point, you already have all the upgrade files ready. Time to roll. Please note that if you are running own custom kernel on 6.2-RELEASE, you should have your custom 8.1 kernel install before attempting this step if. In my attempt, sshd could not be started after reboot as the base is not in sync with the new kernel. Thus, remote binary upgrade from 6.2 to 8.1 seems not possible. Let me know if you experience otherwise or have better method dealing with remote upgrade.
old6# ./freebsd-update.sh -f freebsd-update.conf install
Installing updates...
Kernel updates have been installed. Please reboot and run
"./freebsd-update.sh install" again to finish installing updates.
old6# reboot
The uname shows spanking new 8.1-RELEASE kernel.
old6# uname -a
FreeBSD old6.vnet.0rg 8.1-RELEASE FreeBSD 8.1-RELEASE #0: Mon Jul 19 02:55:53 UTC 2010 root@almeida.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386
New base will be installed in this step. Reboot and you have newly upgraded 8.1-RELEASE FreeBSD.
old6# ./freebsd-update.sh -f freebsd-update.conf install
Installing updates... done.
PORTS
As this is a major upgrade, all ports are recommended to be recompiled. You could use compat6x (misc/compat6x) to minimise downtime if you have many services running on the box.
