	It is probably technically possible.
	However: when jumping major versions, my advice is always "If
possible, install from clean disk."
	On the down-side, it is moderately more work than upgrading.
	On the up-side:

	1) if something goes Horribly Wrong, you're not screwed
	2) you will avoid library version conflicts, and indeed reclaim
		space used by orphaned libraries (and other files)
	3) if desirable, you can re-size partitions

	Others are left as an exercise to the reader.
	In either case: remember to save critical config files
(rc.conf, the kernel config, sshd_config, the named directory, etc.)
elsewhere.
