The upgrade procedure is the same for major upgrade (10.x to 11.x ) as for minor upgrade (10.3 to 10.4). It is recommended to upgrade to the latest 10.x then to 11.x but sometimes I did source upgrade with skipping the whole branch - from 8.4 to 10.1 or 10.2. It worked with one exception but this must be tested first. If you plan to upgrade from 10.x to 11.2 then everything you need is described in /usr/src/Makefile Just checkout the sources in to /usr/src as usual and then For individuals wanting to upgrade their sources (even if only a delta of a few days): 1. `cd /usr/src' (or to the directory containing your source tree). 2. `make buildworld' 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). [steps 3. & 4. can be combined by using the "kernel" target] 5. `reboot' (in single user mode: boot -s from the loader prompt). 6. `mergemaster -p' 7. `make installworld' 8. `mergemaster' (you may wish to use -i, along with -U or -F). 9. `make delete-old' 10. `reboot' 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) I always skip step 5. doing all without reboot but beware of dragons! On upgrade from latest 10 (10-STABLE or 10.4-RELEASE) you may see notices on "make installkernel" phase: kldxref: unknown metadata record 4 in file atacard.ko kldxref: unknown metadata record 4 in file atp.ko They can be safely ignored.
