Compatibility considerations

  • These products are not compatible with vSphere 6.5 at this time:
    • vRealize Infrastructure Navigator
    • Horizon Air Hybrid-Mode
    • vCloud Networking and Security
    • vRealize Hyperic

      Environments with these products should not be upgraded to vSphere 6.5 at this time. This article and the VMware Product Interoperability Matrixes will be updated when a compatible release is available.
  • To revert a migration to 6.5 that contains these products see, Reverting a vCenter Server 5.5 or 6.0 to Appliance 6.x migration (2146453)
  • To revert a Windows installed vCenter Server upgrade that contains these products, see the Roll Back a vCenter Server Instance on Windows When vCenter Server Upgrade Fails section in the vSphere Upgrade guide.
  • If the vSphere 5.x environment utilizes an embedded vRealize Orchestrator instance, its database will not be migrated. The existing vRealize Orchestrator database will need to be exported or export all workflows and configuration prior to upgrading to vSphere 6.5. For more information, see Export the Orchestrator Database.
