Question

A company must vacate its colocation data center in 90 days after a lease was not renewed. The environment contains roughly 250 physical and virtual servers running a mix of Windows and Linux workloads, including several tightly coupled legacy applications whose source code is unavailable. The team has no capacity to refactor or re-architect anything before the deadline, but they want automated, block-level replication with continuous data sync so that final cutover produces minimal downtime and a low RPO. Which approach best meets these requirements within the timeline?

Accepted Answer

Use AWS Application Migration Service (MGN) to install replication agents on the source servers, continuously replicate to a staging area in AWS, then perform test and cutover launches.

Answer

Use AWS Database Migration Service (DMS) with continuous CDC to replicate the servers to AWS and cut over once the target is in sync.

Answer

Order AWS Snowball Edge devices, export VM images and file systems to the devices, ship them to AWS, and import the images as AMIs for launch.

Answer

Re-architect the tightly coupled applications into containers on Amazon ECS and rebuild the databases on Amazon Aurora before the lease expires.
