* After upgrading a previous version to Dokeos 1.6, there are only
* MAX_COURSE_TRANSFER courses converted to the new format - with
* MAX_COURSE_TRANSFER in install/index.php being 100 as default.
*
* To update the rest of the courses you need to run this script.
*
* @package dokeos.install
* @todo remove duplication: MAX_COURSE_TRANSFER is defined here and
