The client had an existing website on Moodle technology and wanted us to upgrade it to the latest version Moodle 3.3.
The main challenge of the project was to upgrade the current Moodle site with the real data of website's live users. Also, the client has various subdomains. So, we had to use the same source code in different databases.
In the first phase of project development, our team of professionals in Moodle, PHP and Mysql successfully upgraded the website from old Moodle 3.2 to the latest version Moodle 3.3. As desired by the client, old Moodle functionality was also implemented to its latest version. All the real data of the users were successfully migrated without doing any modifications in the attributes by making use of the same source code for all different subdomains.
