Technical innovation in university settings often progresses slowly, with legacy systems frequently remaining in use for years. This can lead to outdated technologies that no longer meet user needs. In this demonstration, we explore the revival of such legacy systems through the example of UnivIS, a course administration system used at the University of Bamberg for over two decades. We introduce Baula, a digital study assistant that builds on UnivIS data and functionality, integrating them into a modern, user-friendly interface. By upcycling existing infrastructure, Baula addresses significant student concerns regarding usability and functionality. This demonstration illustrates how such legacy systems can be modernized to better align with contemporary user requirements, showcasing a model for innovation within a traditionally slow-moving environment.
