Understanding why people accept or reject new information systems is an important IS research topic. Successful IT implementation is crucial to an organization's competitiveness but is often challenged by user resistance to accepting new systems. Most existing IT adoption studies focus on assessing the new system itself, while the majority of IT switching studies focus on examining and comparing different types of switching costs. However, little research has leveraged both perspectives to investigate the impact of users' beliefs about the prior system on their perception towards the new system. By combining the two perspectives, this research in progress proposes an integrated framework including a comprehensive set of IT adoption and switching cost factors. We plan to empirically examine this framework in an e-learning context for two reasons. First, research on e-learning system switch is rare. Second, an ongoing e-learning system transition at the authors' institution provides an ideal empirical setting.
