I use the following procedure:
1) build freebsd in a CLEAN machine (supose new bsd is 8.2)...:
    make buildworld buildkernel
    Please save the environment variables KERNCONF

2) copy /usr/src /usr/obj to the old (8.1, or even 7.x) bsd... in the
same directory(/usr/srcj /usr/obj) rsync works fine...
3) in the new (the one you generate freebsd) machine....
    rsync -avz --delete /usr/src/  root@oldmachine:/usr/src
    rsync -avz --delete /usr/obj/  root@oldmachine:/usr/obj
4) in the oldmachine.....
    cd /usr/src
    set KERNCONF
    make installworld installkernel
5) reboot..

FOR ME, it works...
