1. A computer-implemented method for transporting configurations between system landscapes, the method comprising: retrieving a predefined configuration model from a plurality of predefined configuration models electronically stored in a configuration repository, the predefined configuration model providing predefined configuration data for a particular software application, the predefined configuration data defining a desired configuration state, and the predefined configuration model comprising a logical system component that is associated with one or more other components, each of the one or more other components being associated with configuration data of the predefined configuration data; and determining that an existing configuration state of a first system landscape is to be updated to the desired configuration state, and in response: retrieving existing configuration data associated with one or more target systems of the first system landscape, the existing configuration data defining the existing configuration state; comparing the predefined configuration data to the existing configuration data to generate a first delta; determining one or more configuration actions based on the first delta; and executing the one or more configuration actions to update the existing configuration state to the desired configuration state.
