The Administrator Information Page page includes installers for the ZENworks Orchestrator 1.3 Agents and Clients for Windows and various Linux/UNIX machines (see Installing the Agent and Clients from the Administrator Information Page (Unsupported)
in the Novell ZENworks Orchestrator 1.3 Installation and Getting Started Guide). The page has no facility for upgrading an agent or client.
To upgrade, we recommend that you use the methods native to the OS to uninstall an older agent or client from the machine, then install the new 1.3 release of the Orchestrator Agent or Orchestrator Clients.
