Wow, i would suppose you could dump them both to xml files. You can do that in the maintenance directory, example. php dumpBackup.php --full > yourbackup1.xml Then once you have both you could import them into a third wiki, assuming you dont have duplicate articles in both. However you should make sure you dont have duplicates because one will replace the other. On Tue, Sep 13, 2011 at 11:47 AM, Richard Rutenberg <rrutenberg(a)coredial.com> wrote:
