AWS Server Migration Service (SMS) now offers multi-server migration support that makes it easier and more cost effective to migrate applications from on-premises datacenters to Amazon EC2. You can migrate a group of servers as a single unit without having to go through the hassle of coordinating the replication of individual servers or decoupling application dependencies. With multi-server support, Server Migration Service significantly reduces the time to migrate applications and lessens the risk of errors in the migration process.
