update an older i386 CURRENT system to amd64 CURRENT

Hello,

I have an older FreeBSD 9.0-CURRENT system which I want to update to
12-CURRENT:

# uname -a
FreeBSD vm-9Current 9.0-CURRENT FreeBSD 9.0-CURRENT #2 r220692: Sun Apr 17 03:28:12 CEST 2011     guru_at_tinyCurrent:/usr/obj/usr/src/sys/GENERIC i386

To do so without compiling everything from scratch, I transferred
/usr/src (r314251) and /usr/obj to this server, the compilation of
/usr/obj was done on an amd64 server and the same procedure (transfer
of /usr/src and /usr/obj) was also used to update my C720 netbook; the
difference is here that the host which should be update is i386.

The 'make installkernel' did not work:
 
# pwd
/usr/src
# file ../obj/usr/src/sys/GENERIC/kernel
../obj/usr/src/sys/GENERIC/kernel: ELF 64-bit LSB executable, x86-64, version 1 (FreeBSD), dynamically linked (uses shared libs), not stripped

# make installkernel

Also the following did not work:

Is there a way to use this /usr/src and pre-compiled /usr/obj on an i386
host for update? Or do I have to use a complete recompile or even
reinstall, based on a 64-bit memstick system?

Thanks
