VMware HCX enables:
You can schedule and migrate thousands of vSphere virtual machines within and across data centers without requiring a reboot.
Change platforms or upgrade vSphere versions
With HCX, you can migrate workloads from vSphere 5.x and non-vSphere (KVM and Hyper-V) environments within and across data centers or clouds to current vSphere versions without requiring an upgrade.
Workload rebalancing provides a mobility platform across cloud regions and cloud providers to allow customers to move applications and workloads at any time to meet scale, cost management, compliance, and vendor neutrality goals.
Business continuity and protection
Using HCX capabilities, administrators can protect workloads by replicating them to other HCX enabled sites. Workload migration is available on-demand, or it can be scheduled for business or maintenance planning.
