We develop and test a model of migration and use of platforms (MOMnUP) to explain consumers’ reactions to the newest generation of an information and communication technology platform. We draw from information systems and consumer behavior research on adoption and use of technologies, and adapt and incorporate the construct of complementarity from the macro-level research on platform leadership, network effects, and innovation ecosystems. We conceptualize complementarities between the hardware and software platforms, software platform and applications, and applications and services. The complementarities are theorized to influence migration intention, with current generation of the consumer’s platform being a key moderator. We empirically validated our model with data collected using two waves of surveys from 4,412 consumers (2,333 consumers in the second wave) before and after the introduction of the 3^rd generation (3G) mobile data services platform in Hong Kong. We explained 60% of the variance in migration intention that in turn was strongly correlated with migration to and use of 3G.
