About VMware HCX

VMware HCX delivers secure and seamless application mobility and infrastructure hybridity across both on-premises and in the cloud. HCX abstracts the distinct private or public vSphere resources and presents a Service Mesh as an end-to-end entity. HCX Interconnect can then provide high-performance, secure, and optimized multi-site connectivity to achieve infrastructure hybridity and present multiple options for bi-directional virtual machine mobility with technologies that facilitate the modernization of legacy data centers.

For more information, see the VMware HCX User Guide in the VMware Documentation Center.

Upgrade Considerations

  • Upgrading to HCX 4.3.3 is supported only from HCX 4.0.x or later.
  • HCX 4.0.0 is the oldest version suitable for upgrade. Customers running older releases are required to upgrade to HCX 4.0.x first before upgrading to HCX 4.3.3.
  • HCX 4.3.3 is the recommended version for all upgrades to 4.3 from other minor versions (HCX 4.0, 4.1, 4.2).
  • Assistance with upgrading from out-of-support releases is on a best-effort basis and may require redeployment.
  • VMware sends administrative messages to HCX systems that are running out of support and require upgrade. 

Upgrade compatibility information is available as a table in VMware Product Interoperability Matrix - Upgrade Path.
