Phase F: Migration Planning Objectives - TOGAF 10 Foundation Guide
Understanding Phase F: Migration Planning Objectives
Phase F is a critical component of the TOGAF ADM (Architecture Development Method) that focuses on creating a detailed migration plan to transition from the current state architecture to the target architecture. This phase bridges the gap between architectural design and implementation.
Why Phase F is Important
Phase F is essential because:
- Risk Mitigation: It identifies potential risks and dependencies in the migration process, allowing organizations to plan mitigation strategies.
- Resource Planning: It ensures adequate resources are allocated for the transition, including personnel, budget, and technology.
- Sequencing: It determines the optimal order of implementation to minimize business disruption.
- Stakeholder Communication: It provides a clear roadmap that all stakeholders can understand and follow.
- Success Measurement: It establishes metrics and checkpoints to track progress and ensure objectives are met.
What is Phase F: Migration Planning Objectives?
Phase F is the phase where architects and planners develop a comprehensive migration strategy. The primary objectives include:
- Develop Migration Strategy: Create a detailed plan for moving from the current architecture (AS-IS) to the target architecture (TO-BE).
- Identify Transition Architectures: Define intermediate architectural states that may be necessary during the migration process.
- Create Detailed Roadmaps: Develop implementation and migration roadmaps that show the sequence of activities and timeline.
- Assess Implementation Constraints: Identify technical, organizational, and financial constraints that may affect the migration.
- Define Success Criteria: Establish clear metrics and KPIs to measure the success of the migration.
- Plan Resource Requirements: Determine the people, tools, and budget needed for successful implementation.
How Phase F Works
Step 1: Review Baseline and Target Architectures
Begin by thoroughly understanding both the current state (baseline) and desired future state (target) architectures, including all architectural domains (business, data, application, technology).
Step 2: Identify Dependencies and Constraints
Analyze interdependencies between different components and identify constraints such as:
- Technical dependencies
- Organizational constraints
- Financial limitations
- Time constraints
- Regulatory requirements
Step 3: Create Transition Architectures
Define intermediate architectural states if the jump from current to target is too large. Transition architectures serve as stepping stones to reduce risk and complexity.
Step 4: Develop Implementation Roadmaps
Create detailed roadmaps that include:
- Sequence of implementation projects
- Timeline and milestones
- Resource allocation
- Risk and mitigation strategies
- Dependencies between activities
Step 5: Define Success Criteria and Metrics
Establish how success will be measured, including:
- Performance metrics
- Business value realization
- Cost and schedule adherence
- Quality indicators
- Stakeholder satisfaction
Step 6: Plan for Change Management
Develop strategies for managing organizational change, including training, communication, and stakeholder engagement.

Exam Tips: Answering Questions on Phase F: Migration Planning Objectives
Tip 1: Understand the Core Purpose
Remember that Phase F is specifically about planning the migration, not executing it. Questions often test whether you understand the difference between planning and execution. Focus on the strategy and planning aspects.
Tip 2: Know the Sequence Within the ADM
Phase F comes after the architecture design phases (B, C, D) and before Phase G (Implementation). If a question asks about the correct ADM sequence, ensure you can place Phase F correctly. Phase F answers questions about how to get there, not what to build.
Tip 3: Distinguish Between Key Concepts
Transition Architecture vs. Target Architecture: A transition architecture is an intermediate state needed during migration, while the target architecture is the ultimate goal. Questions may test whether you can differentiate these.
Migration vs. Implementation: Migration planning (Phase F) is about creating the transition strategy. Implementation (Phase G) is about executing it.
Tip 4: Focus on the Nine Key Objectives
The nine objectives of Phase F typically include:
1. Determine implementation and migration strategy
2. Determine transition architectures
3. Create implementation roadmap
4. Ensure implementation roadmap addresses the gap analysis
5. Ensure implementation roadmap links to business strategy
6. Ensure implementation roadmap addresses compliance requirements
7. Create sequencing strategy
8. Identify and mitigate implementation risks
9. Plan implementation governance
Tip 5: Remember Risk Management is Critical
Phase F emphasizes risk identification and mitigation strategies for the migration process. Questions may ask how risks should be addressed during migration planning. Key areas include dependencies, resource constraints, and technical challenges.
Tip 6: Recognize the Importance of Stakeholder Alignment
Phase F requires alignment with various stakeholders. If a question asks about engaging stakeholders in migration planning, the answer should emphasize clear communication, buy-in, and managing expectations.
Tip 7: Understand Resource and Constraint Analysis
Phase F includes detailed analysis of:
- Resource requirements (people, budget, tools)
- Organizational constraints
- Technical constraints
- Time-related constraints
Questions may ask how to handle situations where constraints limit migration options. The answer should reflect understanding of trade-offs and alternative approaches.
Tip 8: Know the Difference Between Objectives and Solutions
Phase F is about defining objectives and plans, not solving all implementation details. When answering exam questions, avoid going into execution details that would be handled in Phase G.
Tip 9: Test Your Understanding with Scenario-Based Questions
Exam questions often present scenarios like: "An organization needs to migrate from a legacy system to a cloud-based platform. What should Phase F focus on?" The correct answer would involve:
- Creating a migration strategy
- Identifying transition phases
- Assessing risks and dependencies
- Developing implementation roadmaps
- Defining success metrics
Tip 10: Remember the Governance Framework
Phase F includes planning for implementation governance, which involves:
- Defining decision-making processes
- Establishing oversight mechanisms
- Creating communication channels
- Setting up change control procedures
Example Exam Question and Answer
Question: "During Phase F of the TOGAF ADM, an organization must migrate from its current on-premises infrastructure to a cloud platform. The current state is complex with many interdependencies. What is the most important first step in Phase F: Migration Planning?"
Answer: The most important first step would be to thoroughly analyze the gap between the baseline (current) architecture and the target architecture, including identifying all dependencies and constraints. This analysis forms the foundation for creating realistic transition architectures, sequencing implementation, and planning resources. Only after understanding the scope and complexity can you develop an effective migration strategy and roadmap.
Common Pitfalls to Avoid
- Confusing Phase F with Phase G: Remember Phase F is planning; Phase G is execution.
- Overlooking Transition Architectures: Never assume you can jump directly from current to target state without considering intermediate phases.
- Ignoring Risk Management: Phase F requires explicit identification and mitigation planning for risks.
- Forgetting Stakeholder Engagement: Phase F requires alignment with stakeholders and clear communication of the migration plan.
- Not Linking to Business Strategy: The migration roadmap must align with overall business objectives and constraints.
Conclusion
Phase F: Migration Planning Objectives is fundamental to ensuring successful architecture implementation. By understanding its purpose, key deliverables, and how it fits within the TOGAF ADM, you'll be well-prepared to answer exam questions confidently. Remember to focus on the planning and strategy aspects, maintain clear distinctions between phases, and always consider risk management, resource planning, and stakeholder alignment when answering questions about Phase F.
