This study explore reasons and drivers for replacing on-premise Enterprise Resource Planning (ERPs) systems with cloud-based solutions. The research questions asked was: What reasons and drivers makes an larger organization that has all necessary infrastructure installed and has a working on-premise ERP to replace that with an cloud-based solution. Data was collected through semi-structured interviews from which an thematic analysis was conducted. From the analysis some reasons and drivers were identified, which then was related to earlier gained experience from the literature. The main conclusion is that even if a well working ERP and installed infrastructure exist there are strong reasons and drivers suggested for doing the change. The findings have indicated that the main drivers for large organizations to implement cloud-based ERPs are: the ease of updates, the possibility to scalability and flexibility as well as the potential of having reduced IT costs. The study's contribution lies in the fact that it provides an in-depth understanding of why large organizations choose to implement cloud-based ERPs despite previous investments in on-premise ERPs. © 2025 The Author(s).
