When we consider large/expensive technical products/systems, it is often the case (after some time) that repair is required to replace modules that are not working and no longer commercially available or the functionality of the system needs improving. The problem is to make these changes at minimal cost. We outline a reconfiguration approach within our constraint-based model for the configuration of technical systems, and look at some aspects of its prototypical implementation ConBaCon (Constraint Based Configuration). The integration of a constraint-hierarchy transformer, allowing the computation of improvement instructions and preferences, provides a sound basis for an inexpensive reconfiguration/reconditioning of existing industrial products, including the problem of versioning of technical modules.
