Follow this checklist to be sure your on-premises and SDDC configurations are appropriate for hybrid migration using VMware HCX.

Requirement Description
Networking speed Migration with vMotion using HCX requires a minimum of 100 Mbps throughput between source and destination.
On-premises vSphere version
  • For vMotion: vSphere 5.5, 6.0, 6.5, 6.7
  • For bulk migration: vSphere 5.0, 5.1, 5.5, 6.0, 6.5, 6.7
  • For cold migration: vSphere 5.5, 6.0, 6.5, 6.7
On-premises virtual switch configuration vSphere Distributed Switch
Cisco Nexus 1000v
vSphere standard switch
Installation of VMware HCX Manager in the on-premises data center Install and configure the VMware HCX Manager appliance as described in Introduction to HCX Deployments.
Establish the HCX Interconnect with your SDDC Pair the VMware HCX Manager with your VMware Cloud on AWS SDDC as a remote site as described in Configuring and Managing the HCX Interconnect and Configuring and Managing the HCX Interconnect with the Multi-Site Service Mesh.
L2 VPN Extend a network from your on-premises datacenter to your VMware Cloud on AWS SDDC as described in Extending Networks with VMware HCX.
VMware Cloud on AWS firewall rules Create firewall rules to open the ports used by HCX as described in Network Port and Protocol Requirements.
On-premises firewall rules Create firewall rules to open the ports used by HCX as described in Network Port and Protocol Requirements.
Virtual machine hardware and settings

Ensure that these requirements are met for virtual machine hardware.

  • Virtual machine hardware version and virtual disk size as specified in VMware Configuration Maximums.
  • EVC is not supported in the VMware Cloud on AWS SDDC.
  • VMs that are created in the cloud SDDC or that have been power-cycled after migration to the cloud SDDC can't be migrated back to the on-premises data center with vMotion unless the on-premises EVC baseline is Broadwell. You can relocate these VMs after powering them off, as long as their virtual machine hardware version is compatible with the on-premises data center.

The following virtual machines are not supported:

  • VMs with shared .vmdk files.
  • VMs with virtual media or ISOs attached.
