Before you begin the ZENworks Orchestrator upgrade process, you need to know the underlying assumptions of the process so that you can better understand how to proceed. The following list details the most important of those assumptions:
You can upgrade to ZENworks Orchestrator 1.3 from ZENworks Orchestrator 1.2.x (that is, from version 1.2 and any subsequent patches applied to version 1.2)
To check the installed Orchestrator components for version number, run the following command on a Linux machine where agent, client, or server components are installed.
rpm -qa | grep 'novell-zen'
To check version numbers on a Windows machine, open the
console in Windows and look for the agent or client version number in the programs list.The upgrade of ZENworks Orchestrator must be done for all Orchestrator Server, Orchestrator Console, Virtual Machine Management Interface and all Orchestrator Agent components. Running older agents with newer server components or running older consoles and interfaces with newer server components (or vice versa) is not supported.
Upgrading a prior release of a 32-bit ZENworks Orchestrator installation to a newer 64-bit version of Orchestrator is not supported. Similarly, upgrading a prior release of a 64-bit Orchestrator installation to a newer 32-bit version is not supported.
After you upgrade the server components, older versions of the Orchestrator agents, the Orchestrator Console, and the Eclipse GUI might not work with the newer server components. The Orchestrator Console identifies the managed nodes that have non-compatible agents. For more information about component compatibility, see Section 1.2, Compatibility Checking Behavior.
Errors can occur during the upgrade process. These errors can be resolved and the upgrade process can be re-run. For more information about how the recovery works, see Section 2.1.7, Recovering from a Failed Orchestrator Server Upgrade.
After the Orchestrator Server is upgraded and started, rolling back to a previous version of ZENworks Orchestrator is not supported.
Step-by-step information about the events occurring during the upgrade process is recorded in server.log, located in the /var/opt/novell/zenworks/zos/server/logs directory.
