Novell Documentation: ZENworks 6.5 - Upgrading Workstations

Upgrading Workstations

After you have updated the ZENworks Desktop Management Server and the ZENworks Middle Tier Server, you need to upgrade your workstations.

Listed below are upgrade procedures and software behaviors that you need to know about:

On workstations that are using the Novell Client, upgrade the Novell Client to version 4.9 SP1a. This uninstalls the older Novell Client and installs the 4.9 SP1a version.
On workstations that have the ZfD 4.x Agent installed, install the ZENworks 6.5 Desktop Management Agent. This uninstalls the ZfD 4.x Agent and installs the ZENworks 6.5 Desktop Management Agent.
For installation methods and detailed installation steps, see Installing and Configuring the Desktop Management Agent.
The version of the agent that shipped with ZfD 4.0 (setup.exe) is no longer supported. Prior to upgrading a ZfD 4.0 Agent to ZENworks 6.5, you should replace this older version of the agent with the version of the agent shipping with the ZENworks 6 Suite (ZENworks for Desktops 4.0.1/SP1b) or later.
When configuring the upgrade Application object for the Desktop Management Agent (for use by the Novell Application Launcher), we recommend that you set the application to RUN ONCE so that after the agent is installed the user can no longer see the application in Novell Application Launcher. You should also make sure that uninstall is not enabled for the Application object.
Administrator rights are not needed to upgrade the Desktop Management Agent. The user's privileges are elevated temporarily by the Desktop Management Agent during the installation.
If you upgrade the ZfD 4.x Agent (excluding ZfD 4.0.1 Interim Release 4) to ZENworks 6.5, and if you use a workstation-associated Application object to perform the upgrade, users are not prompted to reboot their workstations.
If you perform the upgrade with a user-associated Application object, the reboot prompt is displayed.
If you want to set the NAL_SINGLE_TREE MSI property when you upgrade the ZfD 4.0.1 Agent (or later, except for Interim Release 4) to ZENworks 6.5, you must also set the ZENWORKS_TREE property and specify the tree from which the workstation will receive ZENworks files.
If you are upgrading the ZfD 4.0.1 Agent from ZfD 4.0.1 Interim Release 4 to version 6.5, you need to set the tree value to the tree where the workstation is imported. If the workstation has not been imported, the setting is ignored.

Pre-upgrade Considerations (Support Pack 2)

If Symantec PCAnywhere 10.x (or earlier version) is installed on the managed device and if you are upgrading the Remote Management Agent, you need to be aware of the following:

Upgrading the Desktop Management Agent with the Mirror Driver Option Selected (Recommended)

Selecting the Mirror Driver option in the Desktop Management Agent installation might cause the managed device to shift to low resolution or VGA mode. This occurs because PCAnywhere does not support coexistence with Remote Control solutions that are based on hook driver technology. The Remote Management hook driver shipping with ZENworks 6.5 Desktop Management has been deprecated and is no longer being installed on the managed device during upgrade.

To resolve this issue, do the following:

Reinstall the system video driver on the managed device.
Reinstall PCAnywhere on the managed device.
Upgrade the ZENworks Desktop Management Agent with the Mirror Driver option selected.

NOTE: You need to execute these steps only once. Because subsequent upgrades will not require these steps, we recommend that you select the Mirror Driver option during installation.

Upgrading the Desktop Management Agent without Selecting Mirror Driver Option

If you choose not to install the mirror driver, you will not encounter the low resolution or VGA screen problem. However, the remote sessions are not optimized for performance if the mirror driver is not installed. For this reason, you need to execute rmsetdrv.exe to enable the hook driver, which is deprecated with ZENworks 6.5.

To resolve this issue, do the following:

Upgrade the ZENworks Management Agent without selecting the Mirror Driver option.
Run rmsetdrv.exe /hook.

NOTE: Because you need to launch rmsetdrv.exe every time you upgrade the agent without selecting the Mirror Driver option, and because the hook driver is deprecated with ZENworks 6.5, we recommend that you select the Mirror Driver option during the agent upgrade.

For more information on rmsetdrv.exe, see TID 10089810 in the Novell Support Knowledgebase.

Rolling Back to the ZENworks for Desktops 4.x Agent

We strongly recommend against rolling back to the ZfD 4.x Agent after you have upgraded to the ZENworks 6.5 Desktop Management Agent. Rolling back (that is, installing the ZENworks for Desktops 4.0.1 Agent or a subsequent patch or interim release while the ZENworks 6.5 Management Agent is still installed) causes the Agent to stop working.

If you need to revert to an older version of the Agent, we recommend that you uninstall the ZENworks 6.5 Desktop Management Agent first, then install the ZENworks for Desktops 4.0.1 Agent.
