What I did to go from 1.2 to -current (Dec 14th sources) was to

1. configure a new kernel config file based on the samples
(specifically, you'll probably need EXEC_ELF32 on the i386 port, if
you're doing Linux emulation).

cd /sys/arch/<arch>/conf
config YOURKERNEL
(cd ../compile/YOURKERNEL; make depend ; make)

Reboot, using this kernel, and the 1.2 binaries.

2. (cd /usr/src; make obj) #You may not want to do this

3. (cd /usr/src/etc ; make DESTDIR=/ distrib-dirs)

4. (cd /usr/src; make build)
