In this paper, we target the critical problem of data management - changing user requirements that need to be reflected in data structures, so-called evolution management. We introduce the first approach to evolution management of multi-model data, considering all popular models and known types of their combinations. We utilize category theory to represent all specifics of the combined models and extend it with schema-modification operations together with respective propagation strategies.
