Is the problem that when you are upgrading the dir is stil lthere and
therefore you can't create the link? If so, you might try 'rmdir' if
the dir is empty or 'mv <olddir>/* <newdir>/' if not (not safe if
there are subdirs).
Truth is it's very hard to do this in maintainer scripts sometimes.
If you're very sure that there's nothing meaningful in the directory
you want to keep around I suggest doing 'rm -f' in 'preinst upgrade
*'. Whatever you do in the scripts, though, be sure you check what
the 'error rollback' maintainer call is and deal with undoing what you
did there (in this case, 'postrm failed-upgrade' and 'postrm
abort-upgrade').
I dunno, maybe someone here can give better advice or you could more
clearly express the issue?
