SMS is a comprehensive, AWS-managed service designed to simplify the migration of servers from on-premises environments to AWS.

It is excellent for organizations that want a highly managed, AWS-guided migration path without needing to manage the underlying replication infrastructure themselves.

help AWS Site Migration Service (SMS) FAQ

What is AWS Server Migration Service used for when moving VMware servers to AWS?

AWS Server Migration Service, commonly called AWS SMS, copies server workloads into Amazon EC2 through an AWS-managed replication process. It was designed for sources such as on-premises VMware environments, so teams could migrate without manually rebuilding every server.

Is AWS SMS the same product as AWS Application Migration Service?

No. AWS Application Migration Service is the newer service for lift-and-shift migrations, while AWS SMS is the older Server Migration Service name used in legacy migration documentation.

Does AWS SMS automatically discover and replicate every server in a data center?

It can help automate discovery and replication for supported source environments, but it still depends on configured connectors, permissions, and supported operating systems. A VMware estate should be tested in a pilot before moving production workloads.

What AWS destination does SMS create for a migrated server?

The normal destination is an Amazon EC2 instance, with replicated disk data used to create the migrated workload. Network settings, security groups, application dependencies, and cutover timing still need separate planning.
