- ==============================================================================
- * In this file we're working on a well-organised upgrade script to
- * upgrade directly from Dokeos 1.6.x to Dokeos 1.8.3
- *
- * For this upgrade we assume there is an old_dokeos directory and the new
- * software is in a new_dokeos directory. While we're busy developing we
- * work in this one - large - separate file so not to disturb the other
- * existing classes - the existing code remains working.
- *
- * This script uses PEAR QuickForm and QuickFormController classes.
- *
- * First version
- * - ask for old version path
- * - check version (1.6.x or 1.8.x, no others supported at the moment)
- * - get settings from old version
- * - perform necessary upgrade functions based on version
- * Future improvements
- * - ask user if she agrees to detected version (chance to cancel)
- * - ability to do in-place upgrade
- * - ability to let old databases remain and clone them for new install so
- * Dokeos admins can have old and new version running side by side
- *
- * @package dokeos.install
- ==============================================================================
- */
- /*
- * ABOUT DETECTING OLDER VERSIONS
- * Dokeos versions 1.6.x and 1.8.x have an installedVersion.inc.php file.
- * In 1.6.x they have a parameter $platformVersion,
- * in 1.8.x a parameter $dokeos_version.
- * The function get_installed_version($old_installation_path, $parameter)
- * can be used to detect version numbers.
