How about high lighting it? Some people just skim the text.

The instructions start out with:

  We do not provide a dedicated upgrade script. This procedure is not
  bullet-proof, or especially recommended; consider it provided as-is,
  to be used at your own risk. It's your responsibility to understand
  what is being done.          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  If you have any doubts, please do a new installation instead of
  blindly proceeding here.

Should this not be enough warning?
