This is what I did: freebsd-update -r 6.3-RELEASE upgrade (got the warning you mentioned) freebsd-update install Got a message about installing kernel updates. Got a new generic kernel in /boot/GENERIC (check to see this exists!) Depending on whether you have console access to the machine or not: 1. If you don't have console access (you are doing this remotely), mv /boot/kernel /boot/mykernel.old and mv /boot/GENERIC /boot/kernel and reboot. This is because you can't (normally) interrupt the loader remotely - unless someone does it for you. Continue from step 3. 2. If you are in front of the machine, reboot. Stop the boot sequence when the boot loader comes up, and escape to loader prompt. Type: unload load /boot/GENERIC/kernel boot 3. You are now running a 6.3-RELEASE kernel, albeit a GENERIC one. Run freebsd-update install again to install the rest of the system. 4. Recompile your custom kernel the usual way, i.e. make buildkernel KERNCONF=MYKERNEL make installkernel KERNCONF=MYKERNEL reboot 5. You are done!
