The easiest would be to

1. cvsup to RELENG_6 (or RELENG_6_0)
2. cd /usr/src
3. make buildworld
4. make buildkernel
5. make installkernel
6. mergemaster -p
7. reboot into single-usermode and verify your new kernel works
8. mount -a
9. make installworld
10. mergemaster
11. reboot

All described in /usr/src/Makefile (and the handbook). You may need to
reinstall some apps, but most should work with compat5x in place.
