This paper reviews the success factors of the digital transformation of higher education institutions based on the experience of Hassan 2 University of Casablanca (UH2C) in Morocco, which is the second largest university in the country. This work is based on the good practices implemented in the university's digitalization strategy during the COVID-19 pandemic. In order to run all the courses online and allow students to properly follow their lessons, the implementation of a robust and secure system is essential. This paper will take stock of the technical infrastructure of the university which has enabled it to support approximately 130,000 users, then the identification of all the services whose university needed to do its distance learning courses well and a proposal for the new system with the minimum of services that users will need to deliver and follow quality lessons.
