One-line summary
Assess migration value and the current estate, prepare the organization and target environment, then migrate in waves, validate, and modernize.
The three phases
| Phase | Main work | Typical outputs and capabilities |
|---|---|---|
| Assess | Inventory, readiness, cost, risk, and business value | Business case, TCO, Migration Evaluator, Discovery |
| Mobilize | Dependencies, skills, landing zone, and migration waves | Action plan, target environment, CAF, Organizations, Control Tower |
| Migrate & Modernize | Replicate, test, cut over, validate, and optimize | MGN, DMS, DataSync, Transfer Family |
Exam focus
- Assess is evaluation, not the start of data movement.
- Mobilize prepares people, skills, networking, identity, security, governance, and waves.
- Migrate & Modernize performs replication and cutover, then applies the appropriate degree of modernization.
- The phases describe project order; the 7Rs describe a strategy per application; AWS CAF describes organizational capabilities and ownership.
Key takeaway
Assess the value, mobilize the foundation, then migrate and modernize.
