Product configurators allow for the generation/administration of valid product variants. For this purpose, a set of rules is filed in the configurator, which describe possible products that consist of a number of components and elements. If the underlying rule world of the configurator changes, for instance, due to a new legislation or the availability of components, etc., product variants that have been valid so far may become invalid. The present paper focuses on an approach to transforming products that have become invalid due to configuration changes back into valid products that are in accordance with the new rule basis. For this purpose, the concept of the fictitious product will be introduced and a two-stage transformation process proposed: In a first step, an invalid product is transformed into a valid fictitious product that is then converted into a valid real product.
