Dynamic software adaptation can cause the running system to be out-of-synchronous with its model, and, thus, make the system model obsolete for the use in consistency checking. In this paper, we propose a framework for ensuring the synchronization between the model and the runtime system during dynamic adaptation. I.e., this framework maintains the high-level model of the runtime system, which is essential for system validation. We are also plugging several model validation tools to the framework, for performing system validation during dynamic adaptation.
