Research in legacy system modernization has traditionally focused on its technical challenges, andtakes the standpoint that legacy systems are obsolete systems, yet they are crucial for anorganization's operation. Nonetheless, it remains unclear whether practitioners in the industry alsoshare this perception. This paper describes the outcome of an exploratory study in which 26practitioners from the industry are interviewed on what makes a software system a legacy system,what the main drivers are leading to the modernization of such systems, and what challenges arefaced during the modernization process. The findings of the interviews have been validated bymeans of a survey with 198 respondents. As it turns out, practitioners value their legacy systemshighly, the challenges they face are not just technical, but also include business and organizationalaspects.
