Which phase in TOGAF focuses on Migration Planning?

The phase in TOGAF that focuses on Migration Planning is Opportunities and Solutions. This phase is critical because it involves identifying and evaluating the various implementation approaches and determining how the organization can effectively transition from the current state to the desired architecture. In this phase, practitioners assess the opportunities available for improvements and changes to the architecture, as well as the solutions that could be implemented to achieve these changes.

During Opportunities and Solutions, the architecture development team prioritizes potential projects based on their feasibility and how well they align with strategic goals. This includes considering the migration paths needed to execute the transition effectively. Migration planning is a crucial aspect of ensuring that the new architecture can be implemented in a structured and organized manner, minimizing disruption to existing operations and maximizing the value obtained from newly introduced capabilities.

The other phases mentioned have different focuses: Architecture Change Management emphasizes maintaining and managing architecture post-implementation, Technology Architecture deals with the technical infrastructure needed for the enterprise architecture, and Implementation Governance involves overseeing the execution of implementation plans to ensure they align with architectural objectives. While these phases contribute to the overall architecture development process, they do not specifically focus on planning the migration as the Opportunities and Solutions phase does.
