I don't have any reason to expect that you *can't* run the script
at this point; but being a cautious person, I would do this at a
point where I was confident I could recover from a backup, and I
would read through the scripts carefully before applying them.
What you want to be really careful that you *don't* do is to modify
or truncate any of the hard-linked files, as they are quite likely
to still be just another name for the same file that is in use for
production under the newer version. You want to simply remove the
older directory entry pointing to the file.
