A company is migrating its three-tier web application from on-premises to the AWS Cloud. The company has the following requirements for the migration process:
✑ Ingest machine images from the on-premises environment.
✑ Synchronize changes from the on-premises environment to the AWS environment until the production cutover.
✑ Minimize downtime when executing the production cutover.
✑ Migrate the virtual machines' root volumes and data volumes.
Which solution will satisfy these requirements with minimal operational overhead?

A. Use AWS Server Migration Service (SMS) to create and launch a replication job for each tier of the application. Launch instances from the AMIs created by AWS SMS. After initial testing, perform a final replication and create new instances from the updated AMIs.

B. Create an AWS CLI VM Import/Export script to migrate each virtual machine. Schedule the script to run incrementally to maintain changes in the application. Launch instances from the AMIs created by VM Import/Export. Once testing is done, rerun the script to do a final import and launch the instances from the AMIs.

C. Use AWS Server Migration Service (SMS) to upload the operating system volumes. Use the AWS CLI import-snapshot command for the data volumes. Launch instances from the AMIs created by AWS SMS and attach the data volumes to the instances. After initial testing, perform a final replication, launch new instances from the replicated AMIs, and attach the data volumes to the instances.

D. Use AWS Application Discovery Service and AWS Migration Hub to group the virtual machines as an application. Use the AWS CLI VM Import/Export script to import the virtual machines as AMIs. Schedule the script to run incrementally to maintain changes in the application. Launch instances from the AMIs. After initial testing, perform a final virtual machine import and launch new instances from the AMIs.
