Install 9.1 or 9.2 kernel, reboot, mergemaster -p, installworld, 
mergemaster, zfs upgrade -a, zpool upgrade -a, make-delete-old, stamp 
bootloaders, reboot

Install 10.0 kernel, reboot, mergemaster -p, installworld, mergemaster, 
zfs upgrade -a, zpool upgrade, make-delete-old, stamp bootloaders, 
rebuild/reinstall all ports/packages, make delete-old-libs, reboot

Now you're done

I find this easier to do than with freebsd-update, but I'm sure you 
could go that route too. I just prefer the control.


I have a quick and dirty script for automating the stamping of 
bootloaders: https://feld.me/freebsd/bootcode-update.sh
