Migration planning (Phase F)

In this phase, we start looking at how to migrate from the current baseline architecture to the desired target architecture.


The inputs of this phase are:

  1. External reference materials.
  2. Request for Architecture Work (optional) (Prelim Phase).
  3. Capability assessment (Phase A).
  4. Communication plan (Phase A).
  5. Organization Model for Enterprise Architecture (Prelim Phase).
  6. Governance Models and Frameworks.
  7. Tailored Architecture Framework (Prelim Phase).
  8. Approved Statement of Architecture Work (Phase A).
  9. Architecture vision (Phase A).
  10. Architecture Repository.
  11. Draft architecture documents and draft requirements (BDAT).
  12. Change requests for existing business programs and projects.
  13. Architecture roadmap, version 0.1 (Phase E).
  14. Capability assessment.
  15. Implementation and migration plan, version 0.1 (Phase E).


The steps included in this phase are:

  1. Confirm management framework interactions.
  2. Assign a business value to each work package.
  3. Estimate resource requirements, project timings, etc.
  4. Prioritize the migration projects.
  5. Confirm the architecture roadmap and update the architecture definition document.
  6. Generate implementation and migration plan.
  7. Complete the architecture development cycle, lessons learned.


At the end of this phase, the following outputs are generated:

  1. Implementation and Migration Plan, version 1.0.
  2. Finalized architecture definition document.
  3. Finalized architecture requirements.
  4. Finalized architecture roadmap.
  5. Reusable Architecture Building Blocks (ABBs).
  6. Request for Architecture Work for the next ADM cycle (if any).
  7. Implementation of the governance model.
  8. Change requests for architecture capability from lessons learned.
