HCX is the recommended migration tool for moving VMware workloads to and from the cloud. While HCX has been used from on-premises DC to the cloud (and vice-versa) and between DCs, it didn’t have the ability to offer workload migration within the cloud. The new Cloud-to-Cloud enables customers to bulk migrate workloads from their VMware Cloud on AWS Software-Defined Data Center (SDDC) to another VMware Cloud on AWS SDDC.
