Viewing an earlier version of a package (CM tool integration)
1. From Windows Explorer, create a folder
2. From the CM tool, perform get operations to populate the folder you created with the required version of the Package, and its associated IDF file.
3. From Modeler, ensure that the Package you are going to overwrite is not checked out.
* 
If the Modeler Package is checked out, you may mistakenly check in an older version of the Package.
4. Right-click the Package you want to overwrite with an earlier version, point to Tools > Package Import/Export, and then click Update Existing.
5. Select the folder you created in step 1, and then click OK.
