Migration progress is stored in the AWS Migration Hub home Region
When you’re ready to migrate, use the migration tools that best fit your needs. Options include AWS Application Migration Service (Application Migration Service), AWS Database Migration Service (AWS DMS), or one of many third-party tools.
Migrate your servers and applications into any AWS Region, and the migration progress reported by each tool is stored in your home Region. Stored data provides a single discovery and migration planning repository for your entire portfolio, and a single view of your migrations in multiple AWS Regions.
Authorize your migration tools, such as Application Migration Service, to read discovery data from and send migration status to Migration Hub in your home Region. The migration tools read application groupings and send basic identifying information for each resource. For example, the hostname, IP address, MAC address, and VMware or hypervisor identifiers are sent, along with the resource’s migration status, from the migration’s destination Region to the Migration Hub home Region.
