One of the possible ways (compile from sources):
Say, /path/to/src8 is path where your RELEASE_8 sources are and
/path/to/root8 is path where you have mounted partition dedicated to RELEASE_8.

cd /path/to/src8
make buildworld
make buildkernel
make DESTDIR=/path/to/root8 installkernel
make DESTDIR=/path/to/root8 installworld
make DESTDIR=/path/to/root8 distribution

You have to manualy edit /path/to/root8/etc/fstab and figure out how
will you boot new system.
Also note that it is better to make new partition clean before
the above mentioned procedure (you don't need the copy of RELEASE_7).
It is also irrelevant where do you have RELEASE_8 sources.
