As of /usr/src/UPDATING:
To update from 4.0-RELEASE or later to the most current
4.x-STABLE
----------
make buildworld
make buildkernel KERNCONF=YOUR_KERNEL_HERE
make installkernel KERNCONF=YOUR_KERNEL_HERE
reboot (in single user) [1]
make installworld
mergemaster [2]
reboot
In single user mode only the root fs is mounted by default. So for making installworld
you have to mount all the slices affected by such a process (usually all other slices like
/usr, /var), and also, only the system itself boots up, nothing else is started
preventing any problem caused by installing something new under a running old task
in memory. If the new kernel fails you can return to the old one without risking
incompatibility with the old kernel and the new world. Everything in this order has a
reason :).
