In the ever-evolving landscape of enterprise architecture, successful transformation requires meticulous planning and execution. TOGAF (The Open Group Architecture Framework) offers a structured approach to achieving this transformation, and Phase F, known as “Migration Planning,” stands as a pivotal stage in this journey. In this article, we will delve into the essential aspects of Phase F, highlighting its significance, objectives, and key activities. By the end of this exploration, you will have a clear understanding of the role Migration Planning plays in the TOGAF ADM and how it propels organizations toward their desired architectural future.

Migration Planning in TOGAF

In TOGAF (The Open Group Architecture Framework), Phase F is called the “Migration Planning” phase. This phase is part of the Architecture Development Method (ADM) and plays a crucial role in the development and execution of an enterprise architecture.

Here’s an overview of what happens in Phase F of the TOGAF ADM:

  1. Objective:
    • The primary goal of Phase F is to develop a detailed plan for implementing the target architecture that was defined in previous phases of the ADM (Phases B, C, and D). It focuses on creating a structured roadmap for transitioning from the current state to the desired future state.
  2. Status at this Point in the ADM:
    • By the time Phase F begins, you should have already completed the following phases: Preliminary Phase (Phase A), Architecture Vision (Phase B), Business Architecture (Phase C), and Information Systems Architecture (Phase D).
    • You should also have a well-defined Target Architecture that has been approved by stakeholders.
  3. Activities in Phase F:
    • Finalize the Architecture Roadmap: In this phase, you refine the high-level architecture roadmap developed in earlier phases. You identify and sequence the transition initiatives necessary to achieve the target architecture. These initiatives are often organized into projects, programs, or portfolios.
    • Develop Migration Plans: For each transition initiative, you create detailed migration plans. These plans outline the steps, resources, and timelines required to implement the changes. They also consider factors like budget, risk, and dependencies.
    • Identify and Document Interactions: You assess the interactions and dependencies between different migration initiatives and document them. This helps in managing and coordinating the implementation efforts effectively.
    • Risk Assessment and Mitigation: Identify potential risks and challenges associated with the migration initiatives and develop mitigation strategies.
    • Financial Considerations: Develop cost estimates and budget requirements for each initiative to ensure alignment with the organization’s financial resources.
    • Architecture Contracts: Establish architecture contracts with the responsible parties or stakeholders involved in the implementation of each initiative.
  4. Deliverables:
    • The primary deliverable from Phase F is the Detailed Migration Plan, which includes detailed information about each transition initiative. This plan should be comprehensive and actionable.
    • Other potential deliverables may include updated versions of the Architecture Roadmap, risk assessments, and financial plans.
  5. Next Phase:
    • The next phase in the TOGAF ADM after Phase F is Phase G, which is called “Implementation Governance.” The detailed migration plans developed in Phase F are used as inputs to Phase G. Phase G focuses on overseeing and managing the execution of the transition initiatives to ensure that they align with the architecture vision and goals.


Phase F in the TOGAF ADM is where you take the high-level target architecture and create detailed migration plans for transitioning from the current state to the desired future state. It involves careful planning, risk assessment, budgeting, and coordination of initiatives. The output of this phase, the Detailed Migration Plan, is essential for the successful execution of the architecture roadmap in subsequent phases.
