In one sentence
Start with business goals, application portfolio, dependencies, migration strategy, cutover and rollback, and post-migration modernization.
Core summary
Structure the program as Assess, Mobilize, and Migrate & Modernize. Build waves from dependencies and risk, starting with a low-risk pilot.
Study points
- For low-downtime servers, use MGN block replication, testing, and cutover.
- For heterogeneous databases, convert schema and code, then use DMS full load and CDC.
- DataSync moves files, Transfer Family exposes transfer protocols, and Direct Connect provides a network path.
- A backup plan still needs assignments, permissions, recovery points, and real restore validation.
Common pitfalls
- MGN supports planned migration; DRS supports ongoing disaster recovery and failback.
- Low downtime is not zero downtime; every cutover needs acceptance and rollback criteria.
Key memory
Discover and assess, choose strategies and waves, test before cutover, and always prepare rollback.
