Fedora :: Coverting Symlinks To Hardlinks

I'm wondering if there is a safe and reliable way of converting symlinks to directories to hardlinks? Basically I have a bunch of files in a directory tree under directory A, and I have in another directory B a set of symlinks to the original site. I would like all the files to end up in B and A to be empty. The links are all to directories, not to files, so the soft2hard script here won't work.

I don't have enough free diskspace to copy the files from A to B so I thought that converting the softlinks to hard links and then removing directory A would work? There are many directories, so would like to do it automatically if at all possible.

(In case anyone is intrigued, the issue is with my maildir directory. I used to use kmail, but with the move to kmail2 it became buggy and virtually unusable with large amounts of mail and I had to find another solution. I now use dovecot with gnus and mutt as MUA to access the maildirs. kmails maildirs are non-standard (!), so with the help of a script I found online, I created ~/dovecot and in it put symlinks to all the maldirs under ~/.kde/share/apps/kmail. The problem with this is if I accidentally start kmail it will try to access that directory and mess up all my tags, so I want to completely move all my mail from ~/.kde/share/apps/kmail to ~/dovecot, but without messing up all my tags etc.)
