The license right of a “downgrade“ was once very common, nowadays not anymore. Actually, they still are valid to some older products and their license politics. If the software producer grants downgrade rights, it means that you can purchase a higher version of a product but install a lower and older one. Many producers and therefore the resellers only sell the latest versions to make their support an easier task. Of course, they don’t want to force their customers to update each pc of the network immediately. To achieve this, they offer downgrade rights for the latest products in some cases.
The Lan-Inspector can map those downgrade rules. They can be managed in the editor for downgrade rules.
