What is the main purpose of the Migration Planning phase in TOGAF?

The Migration Planning phase in TOGAF is primarily focused on creating a roadmap for implementing architecture incrementally. This phase is critical because it involves defining how the transition from the current architecture to the desired future architecture will occur. The roadmap outlines the various steps, timelines, and dependencies necessary for successful migration, ensuring that the implementation aligns with organizational goals and user needs.

By breaking down the migration into manageable phases, organizations can minimize risks and manage resources more effectively. This structured approach allows for adjustments along the way based on feedback and changing circumstances, which is essential in a dynamic business environment. The roadmap includes identifying key milestones, prioritizing initiatives, and clarifying responsibilities, all of which are fundamental to successful architecture evolution.

While evaluating existing architecture, defining the technology stack, or assessing training needs may play a role in the overall architecture vision and migration strategy, these activities are not the primary focus of the Migration Planning phase. Instead, the emphasis is on the comprehensive planning required to ensure a smooth transition between different architectural states.
