In the near future, service-oriented architectures will predominate in the field of software engineering, according to the consensus. Because of the possible benefits, software product makers are interested in migrating to cloud environments. When an existing software system is transformed from the Software as a Product model to the Software as a Service model, the software engineering process is modified. Although sufficient research has been conducted on the process in general, very little effort has been devoted to comprehending how the influence would be felt throughout the requirements elicitation phase. In this paper, we analyse the required changes that need to be made to the requirements engineering process and provide a methodical approach for successfully implementing such changes. In addition, it discusses the new benefits associated with the cloud-native elicitation of requirements. The paper then examines the problems that were found and the solutions that were developed in connection to the derived guidelines and best practises. When transitioning from a typical software product to a model based on software as a service, we have concluded that the requirements engineering process can benefit from a methodical change.
