Abstract Cloud computing is being rapidly adopted by both public and private sector organizations. However, Migration of existing applications into a cloud environment is not trivial; and it involves multiple facets.While the functional requirements are handled by the IT experts, the non-functional and organizational aspects like security, privacy, complaince, etc. need to be addressed by the appropriate stakeholders. This is a comprehensive and involved process. The stakeholders need to be exhaustive in their research and planning to ensure a smooth and successful migration.

In this work, we propose a generic, model-driven, platform independent process model that will help the different stakeholders in the enterprise to take a systematic approach in their journey towards cloud migration. It does so by ensuring both IT and business experts work colloboratively in an efficient manner to avoid potential pitfalls. The issues with different types of cloud migration scenarios are addressed with this generic process model.

The proposed process model is validated by applying it to three different real-life cloud migration scenarios.
