The significance of component-based software and component platforms has increased over the last twenty years. To achieve full flexibility, a reconfiguration process is needed that allows us to change system parameters without rebuilding or restarting. In terms of components, such a process should be executed with extraordinary care, since the contracts between components must be preserved. In this article, a model of reconfiguration (including the roles of the components to be used in this process) is proposed. The provided solution is general and could be applied to many component platforms.
