Built-in testing makes it fast and easy to validate before you migrate. And fast on-premises rollback provides a safety net when the unexpected happens. No software agents means no impact on the resources needed by the workload itself, no need to open access to or from the network where the workload is running, and the ability to complete your migration without the source systems running at all. And with workloads that begin within minutes, downtime is minimal, up front, and predictable.
