Key use cases for HCX+ are the ability to provide workload mobility and network connectivity between paired sites.

Workload Migration

Using HCX+, you can migrate workloads bi-directionally between VMware SDDCs in the same and different sites using various migration types.

Replication Assisted vMotion (RAV)

RAV migration uses both VMware Replication and vMotion technologies for large-scale, parallel migrations with no service interruption. This method migrates waves of virtual machines (VMs) in environments where no downtime is a requirement. RAV migration allows for scheduling migration operations. RAV is the default migration method for most mobility operations.


Bulk migration uses VMware vSphere Replication protocol to move waves of virtual machines in parallel between managed sites that can tolerate some downtime. The Bulk migration type allows for scheduling migration operations.


vMotion migration uses the VMware vMotion protocol to move a single virtual machine between managed sites with no service interruption. The vMotion transfer captures the virtual machine active memory, its execution state, IP address, and MAC address.

Workload migration supports data center consolidation and overall cloud adoption.

Network Extension

Network Extension extends the virtual machine networks from one managed site to a second managed site. Virtual machines that you migrate or create on the extended segment at either site are layer-2 adjacent to all virtual machines placed on the extended network. HCX+ supports extending networks from VMware vSphere Distributed Switches, NSX segments, and NSXv logical switches.

Network Extension supports rebalancing workloads across managed sites.

If virtual machines selected for migration operations are on an extended network, HCX+ selects the same network for placing the migrated workloads. You can also manually modify the destination network, depending on the migration type selected.
