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.

    • Upgrading to HCX 4.4.2 from other versions requires a full upgrade to 4.3.3 first.

    • All site paired systems must be upgraded.

    • When upgrading to HCX Manager 4.4.2 from a version prior to 4.4.0, you must upgrade all Service Mesh appliances to 4.4.0 or later.

  • Upgrade snapshots :

    • During upgrades to HCX 4.4.2, HCX Manager snapshots are taken automatically.

    • Upgrade snapshots are only taken when an HCX Manager is deployed on the same vCenter Server registered to it. For other deployments, manual snapshots can be taken.

    • HCX retains automatic snapshots for 24 hours before deleting them.

  • 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.
