5-118 Installing and Using UtilitiesTIPS:Prerequisites, page 5-92Displaying the Upgrade Summary, page 5-131Selecting Other Configurations to IncludeUse the Other Configurations page to optionally call one or more existing configuration files intothe configuration file you are currently editing, so that the settings from the called files will alsoapply to the file you are editing. This is known as nesting files, or creating nest files.The configuration files that you call into the current configuration file are child configurations, andthe file from which you call the child configurations is the parent configuration.Potential uses for the nest files include:• Your support provider creates a configuration file that you can call into an existingconfiguration file for your system.• You create separate configuration files, each for upgrading a different application, which youcan enable or disable as necessary in your parent configuration.• You create a configuration file for an application that runs on several of your systems and callthat file into a parent configuration file that is specific to each system.The following restrictions apply to the nest files:• Child configuration files must be located in the same directory as the call target files.When you select configuration files in the Active Upgrade Console, only the files inthe current working directory are displayed.• If a call-target configuration files have more than one child configuration files, they alsobecome a part of your configuration.• If a setting in a child configuration conflicts with a setting in the parent configuration,the Active Upgrade Console uses the setting in the parent configuration; the parentconfiguration always ignores disk selections from child configurations.• If you call a configuration created on a different system, configuration items (such asapplication services and custom actions) must be present and applicable on the current system;otherwise, the parent configuration will fail the readiness check.
