VMware Cloud on AWS supports several ways to migrate your workload VMs from your on-premises hosts to the ones in your SDDC and back again, as well as across hosts in your SDDC. The method you choose should be based on your tolerance for workload VM downtime, the number of VMs you need to move, and your on-premises networking configuration.

Migration within the SDDC

Migration within SDDC refers to migrating virtual machines in your SDDC vCenter Server from one host or cluster to another. For information about migrations like this, see Migrating Virtual Machines in the VMware vSphere Product Documentation.

For a guided migration experience to help you use HCX to migrate VMs from your on-premises data center to the cloud SDDC, you can use the VMware Cloud Migration solution, Integrated Experiences for your Hybrid Cloud.

Hybrid Migration

Hybrid migration refers to migrating virtual machines between two different vSphere installations: one that's in your on-premises data center and another that's in your VMware Cloud on AWS SDDC. Because these two vSphere installations might have different versions, configurations, or both, hybrid migration use cases typically carry additional prerequisites and configuration that ensure both compatibility of the virtual machines and appropriate network bandwidth and latency. VMware Cloud on AWS supports a variety of tools and methods for hybrid migration.
