API Reference > imodeljs-backend > iModels > IModelTransformOptions > isReverseSynchronization isReverseSynchronization isReverseSynchronization: undefined | boolean Flag that indicates that the current source and target iModels are now synchronizing in the reverse direction from a prior synchronization. The most common example is to first synchronize master to branch, make changes to the branch, and then reverse directions to synchronize from branch to master. This means that the provenance on the (current) source is used instead. note This also means that only IModelTransformer.processChanges can detect deletes.
