    I would boot with the 5.1 live CD and backup all the data you want to
    save somewhere (like to another machine), then I would reinstall the
    system from scratch with the release you intend to run, wiping the disks
    completely.  Then restore the data you wanted to keep from whereever you
    saved it.

    If you have a lot of data and a reasonably fast network link and no
    place to temporarily backup your data too while reinstalling, I can
    provide you with a temporary account with lots of disk space for a few
    days.  EMail me privately if you need the temporary account.
