The migration tool enables companies to from their data center or other hosting platforms to AWS. As application and data are migrated to AWS, the tool allows the source location to continually operate. Once the application is migrated to AWS environment, a connection is established. The tool recognizes the application service and begins to replay transactions processed in the source location to the migrated application in AWS during the migration exercise. This activity fully synchronizes both the source and target environments and is transparent to the application users and introduces no downtime.
