I have done quite a few upgrades from 4x to current successfully. The reason I did this rather than a full reinstall was the boxes didnt have cds, didnt boot usb, and i dont have floppies anymore. Anyway this is what i found the most reliable way of doing it 1. back it all up 2. download base and kernels distro directories 3. "./install.sh generic" in the kernels dir 4. chflags noschg /kernel 5. mv /kernel /kernel.old 6. ln /boot/kernel/kernel /kernel 7. Reboot to single user 8. mv /etc/ etc.old 9. cd to base dir and "./install.sh" (overwrite it all) (you usually get a few errors but ignore them) 10. copy relevent bits from /etc.old to /etc You might be able to get away with it but I always do a make world and kernel at this point. To doubly make sure everything is there and installed correctly now for the local packages you have two options: rebuild or install compatibility libraries I usually go for rebuild 1.mv /usr/local /usr/local.old 2. mv /var/db/pkg /var/db/pkg.old 3. reinstall ls /var/db/pkg.old/| while read f; do pkg_info -o $f| tail -2; done | sed -e "s/^.*\///" | sort -uls /var/db/pkg/| while read f; do pkg_info -o $f| tail -2; done | sed -e "s/^.*\///" | sort -u | while read p; do pkg_add -rv $p; done 4. copy your configs accross from the /usr/local.old dir Finally after you have tested and are happy all is ok cleanup rm -rf /usr/local.old /var/db/pkg.old cd /usr/src yes | make delete-old-files delete-old-libs delete-old-dirs Its a bit long winded but does work and you end up with a fairly clean install. You can speed up the process by doing the buildworld and buildkernel on another box and nfs exporting /usr/src and obj to the target system
