Techniques and solutions are provided for maintaining data separation, such as when consolidating data for two instances of a data artifact. If data separation is not maintained, it may not be possible, or as easy, to determine from which instance particular data came, which can also limit filtering/selectively searching data for a particular instance. The present disclosure addresses this issue by providing a consolidation data artifact. For particular sets of data in the consolidation data artifact, the consolidation artifact maintains the data in association with an identifier of the instance that serves as the source of the data.
