Because large enterprises must often perform phased upgrades, components are designed to be somewhat forward and backward compatible, at least during upgrades.
The following versions are supported for upgrading to Horizon 7:
- Latest maintenance release of Horizon View 5.3
- Latest maintenance release of VMware Horizon 6.0 (with View)
- Latest maintenance release of VMware Horizon 6 version 6.1
- Latest maintenance release of VMware Horizon 6 version 6.2
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
Horizon Connection Server compatibility with Horizon Agents is limited to interoperability during a Connection Server upgrade. You must upgrade View Agents or Horizon Agents as soon as possible to match the version of the Connection Server that manages them.
The following table lists the components and show whether they are compatible with other components whose version is different.
|Connection Server: Earlier Version||Security Server: Earlier Version||View Composer: Earlier Version||View Agent: Earlier Version||Horizon Client (Windows): Earlier Version|
|Connection Server 7.0||Only during upgrade||Only if paired before upgrade||No||Only during upgrade||Yes|
|Security Server 7.0 (PCoIP and RDP)||No||N/A||No||Only during upgrade||Yes|
|View Composer 7.0||Only during upgrade||Only during upgrade||N/A||Only during upgrade||N/A|
|Horizon Agent 7.0||Only during upgrade (see the exception in the note following this table)||No||No||N/A||Only during upgrade|
|Horizon Client 4.0||Yes||Yes||Yes||Yes||N/A|
