	While I 've done source upgrades across major version bumps, my
recommendation is (if at alll feasible) to buy a new disk and start
over.  It's amazing the amount of crud that accumulates on most
people's disks.  Mount the old disk read-only, and copy off any
desired files, then store it as "ultimate backup" for six months or
so.
