You can export one version of an object at a time. When you export an object from the Navigator or workspace, the PowerCenter Client exports the latest version of the object. If you want to export an earlier version of an object, you can select it from a query result or object history. In the View History or Query Results window, select the objects to export and choose Tools-Export to XML File. You can select multiple object versions to export, but the PowerCenter Client exports only the latest version selected for that object.

For example, the query results contain two mappings that use different versions of the same source. If you export both mappings, the PowerCenter Client exports the latest version of the source.

When you import an object that exists in the target folder, the PowerCenter Client handles object versions differently depending on how you resolve the object conflict. You can resolve an object conflict by replacing, renaming, or reusing the object.

For example, the target folder contains a target called WEEKLY_ORDERS and the latest version is three. You import a target with the same name. When you replace the target, the PowerCenter Client changes the existing target definition to version four. When you reuse the target, the PowerCenter Client does not change the version of the existing target definition. When you rename the target, the PowerCenter Client creates a new target definition and assigns it a version of one, and does not change the version of the existing target definition.
