Instead of AWS Transform MGN (formerly AWS Application Migration Service)
AWS Transform MGN (formerly AWS Application Migration Service) alternatives
AWS Transform MGN moves physical, virtual, and cloud servers into native Amazon EC2 instances. It continuously replicates source servers at block level, converts them for AWS, and coordinates cutover with minimal downtime. Teams can manage rehosting in the MGN console or use an agentic AWS Transform workflow, switching between them without losing progress. Application and wave controls help coordinate larger migrations, while post-launch actions can include operating system upgrades, disaster recovery configuration, and license conversion.

Its focus is server rehosting, so database conversion, migration assessment, and containerization may call for a different tool. MGN supports x86 sources and replication volumes only up to 16 TB. The free period covers 90 days of service charges per source server; AWS infrastructure used for replication, testing, or cutover costs extra, and continued replication is charged hourly afterward. When switching, weigh the target cloud, workload type, need for conversion or assessment, source limits, and how service and infrastructure charges apply.
