API Reference > imodeljs-backend > iModels > IModelTransformOptions > wasSourceIModelCopiedToTarget wasSourceIModelCopiedToTarget wasSourceIModelCopiedToTarget: undefined | boolean Flag that indicates that the target iModel was created by copying the source iModel. This is common when the target iModel is intended to be a branch of the source iModel. This hint is essential to properly initialize the source to target element mapping and to cause provenance to be recorded for future synchronizations. note This hint is typically only set for the first synchronization after the iModel was copied since every other synchronization can utilize the provenance.
