Massive open online courses are a promising area of interest of higher education institutions in their competition for students. However, typically specialised open platforms are used to create such courses, while courses in higher education institutions are delivered through learning management systems. Thus, a higher education institution meets a severe challenge if it decides to offer its study courses as massive open online courses: the content hosted in the learning management system need to be transferred to another platform or re-created. The automated tools developed for this purpose could (at least partially) speed up the learning content migration process while also reducing the amount of manual work required. The paper presents the research results achieved regarding the migration of the content of Moodle courses into Open edX through the use of the cloud-based automated migration tool. The conceptual migration model is described first. After that, some technical details of the developed tool are discussed. Finally, the experimental testing results of applying the tool to three Moodle courses are also specified.
