You were actually right the first time about posting this in our MySQL forum, boham. (I deleted your post in here though). Regardless, what you're going to want to do is do a database dump of the old installation and run the queries to populate the new database. Do you have shell access on either the old or the new PHPNuke installations? What about phpMyAdmin?
