Prior to ZENworks 6.5, distribution rules were known as system requirements and did not include the ability to use both AND/OR Boolean operators and to create groupings of rules. Because of the new operators and groupings, Application Launcher versions prior to ZENworks 6.5 cannot understand distribution rules.
To ensure that pre-ZENworks 6.5 versions of Application Launcher can continue to work in a ZENworks 7 environment, the pre-ZENworks 6.5 system requirements are preserved as legacy system requirements. Therefore, in a mixed-version environment, you need to decide how you want to use distribution rules and legacy system requirements together. You have the following options:
Define distribution rules only: The ZENworks 6.5 (or later) version of Application Launcher can read the distribution rules. Pre-ZENworks 6.5 versions cannot read the distribution rules and therefore are unable to distribute the application.
Define distribution rules and legacy system requirements: ZENworks 6.5 (or later) versions use the distribution rules and pre-ZENworks 6.5 versions use the legacy system requirements. This method enables you to maintain the legacy system requirements for pre-ZENworks 6.5 Application Launcher while using the grouping, operator logic, and new rules available beginning with ZENworks 6.5. If you use this method, you can define the legacy system requirements first and then use them to populate the distribution rules. After populating the distribution rules, you can modify them to meet your needs.
Define legacy system requirements only: Both ZENworks 6.5 (or later) and pre-ZENworks 6.5 versions use the legacy system requirements. This solution reduces administrative maintenance of distribution rules and system requirements, but excludes you from using the new grouping, operators, and rules. Be aware that if you define any distribution rules, ZENworks 6.5 (or later) versions of Application Launcher use the distribution rules, not the legacy system requirements. The ZENworks 7 Application Launcher checks first for the existence of distribution rules; only if no distribution rules exist does it then check for legacy system requirements.
If you have Windows NT 4 workstations in your environment that you are continuing to manage through the use of the ZENworks for Desktops 4.0.1 version of Novell Application Launcher, you need to retain your legacy system requirements.
