Upgrade steps to VMware Horizon View 5.3 are quite the same of the upgrade to 5.2 and also their behavior and order remain the same:

  • Check-list for HCL and also software compatibility (remember to verify also the version of VMware vSphere)
  • Connection servers (included View Manager, Secure Servers and Transfer Servers): remember that for View Secure Servers this is almost a full reinstallation (so pairing must be done from scratch)
  • Composer Server: this must still be a Windows Server (could be vCenter Server, if Windows, or an external server)… remember to keep the existing certificate and DSN.
  • View Agent (and maybe before it the VMware Tools)
  • View Client

Also GPO must be updated on your AD DCs:


Finally you can optionally also add the VMware Horizon View 5.3 HTML5 Access and the Unity part included in the Feature Pack:


Remember to open also the firewall ports for Blast protocol on the VMware View Connections Server:


Also the virtual desktops must be upgraded in order to add the agent part of the feature pack.
