In versions since Blackboard Learn 9.1 SP 4, the exact settings made at the course level for content, both available and unavailable, are tracked and maintained in the export package.
Prior to Blackboard Learn 9.1 SP 4, only available items were included in a course package when exporting or archiving a course. When importing a course package from a pre-SP 4 environment, items that were unavailable may not be available because the package does not contain the unavailable items. Blackboard Learn can't differentiate between unavailable course tools omitted during export and any new items that were not present in the older version and are set to available by default.
