Because large enterprises must often perform phased upgrades, components are designed to be somewhat forward and backward compatible during upgrades.

The following versions are supported for upgrading to VMware Horizon 8:

  • VMware Horizon version 7.x

To determine the latest maintenance release of a particular component, see the Release Notes for that release, available from https://docs.vmware.com/en/VMware-Horizon-7/index.html

In general, it is recommended that you install the same version of Horizon Connection Server as the Horizon Agent in your environment. Though a later version of Horizon Connection Server is supported with an earlier version of Horizon Agent during a pod upgrade, it is preferable to upgrade the Horizon Agent version to the same version as the Connection Server as soon as possible.

The following table lists the key components of Horizon 8 and displays version interoperability.

Table 1. Compatibility Matrix for Horizon 8 Components
Horizon 8.x Connection Server: Earlier Version Horizon 8.x Agent: Earlier Version Horizon Client: Earlier Version
Horizon 8.x Connection Server Only during upgrade Only during upgrade No
Horizon 8.x Agent Only during upgrade N/A Only during upgrade
Horizon 8.x Client Yes Yes N/A
