Update existing command (CM tool integration)
You use this command to overwrite a Package with a previous version of its associated Package in the CM tool. This is useful under the following circumstances:
When you want to view a previous version of a Package in the Modeler environment.
When you want to base a new Package on a previous version of a CM tool Package.
When you want to revert back to an earlier version of a CM tool Package.
When you want to get the latest version of a shared package that resides in a folder, which you will want to do when sharing packages without a CM tool.
This command appears on the context menu when you right-click a Model or Package, and then point to Tools > Package Import/Export.
Before using this command, you must use a CM tool get operation to populate a folder with the version of the Package you require, including its associated IDF file. You can then use this command to overwrite the Package with the version of the Package in the folder.
To use this command you require a Modeler license and a CM Integration license. In addition, this command is not available when the CM tool integration is disabled - you can enable and disable the CM tool integration through the Enable Configuration Management Integration check box for the General entry on the Tool Options dialog.

An IDF file is a text file that contains the name of its associated Package or Model.
