Alibaba Cloud Server Migration Center vs AWS Transform MGN (formerly AWS Application Migration Service)

Alibaba Cloud Server Migration Center has no write-up on Specifiction yet; its figures are above.

AWS Transform MGN automates rehosting physical, virtual, and cloud servers as native Amazon EC2 instances. It continuously replicates source-server data at the block level, converts servers for AWS, and coordinates cutover with minimal downtime. Teams can use an agentic AWS Transform workflow or manage migration steps in the MGN console, switching paths without losing progress. Sources include physical servers, VMware vSphere, Microsoft Hyper-V, other on-premises infrastructure, public clouds, and migrations across AWS Regions, Availability Zones, or accounts. After launch, built-in or custom actions can configure disaster recovery, upgrade operating systems, convert licenses, or install CloudWatch Agent. Servers can be organized into applications and waves for launch, cutover, archival, and configuration operations. MGN supports x86 sources and replication volumes up to 16 TB; larger volumes are not supported. A 90-day free period covers 2,160 hours per source server when used continuously. AWS infrastructure for replication, testing, or cutover is charged separately, and continued replication is charged per hour after the free period.
