Nope, not if you cvsup or use csup (which comes with the system already, most likely) to RELENG_7_2 or RELENG_7, the latter of which would give you 7-STABLE, which is approaching 7.4 nowadays.

Actually, you can run a 7.x userland under a 8.x kernel.
That's how a major version update of FreeBSD from source is supposed to work.  :-)

That should also work.  But it's beneficial to update your sources for the version you wish to run, since you will gain security changes which have been made since....
