What this domain covers

What to know about Accelerate Workload Migration and Modernization

Be able to pick the right migration service per workload (servers, databases, files, large datasets) and design a low-downtime cutover with rollback. The single most important thing: match the tool to the asset type and validate replication before switching traffic.

Selecting AWS Application Migration Service vs DMS/SCT for server, database, and schema migrations

Using CloudFormation, CDK, and Service Catalog to define infrastructure declaratively and repeatedly

Designing replication, cutover, and rollback with minimal downtime using RPO/RTO targets

Choosing rehost, replatform, refactor, or retire strategies and matching tools like DataSync and Snow Family

Watch out for

Common Accelerate Workload Migration and Modernization exam traps

  • ▸Treating DMS as a server migration tool; it moves databases, while Application Migration Service handles block-level server replication.
  • ▸Assuming lift-and-shift is always cheapest; replatforming to managed services often lowers long-term operational cost.
  • ▸Ignoring cutover and rollback planning, so replication lag or schema conversion failures cause extended downtime.
