AWS Application Migration Service (MGN) is Amazon's agent-based rehosting service: it continuously replicates on-premises, virtual, or cloud servers at the block level and converts them into native Amazon EC2 instances with a cutover window AWS documents in minutes rather than hours. It reached general availability in May 2021, superseding AWS Server Migration Service as the recommended lift-and-shift path onto AWS, and in June 2026 AWS rebranded it as AWS Transform MGN, folding it into the AWS Transform family of agentic migration tools while keeping the same replication engine underneath.
