Two-way replicationTwo-way replication allows data changes to be sent multiple times from the parent replica to the child replica or from the child replica to the parent replica. If the same row is edited in both replica geodatabases, it is detected as a conflict when the replicas are synchronized. Reconcile policies are provided to define how conflicts are processed.
Two-way replicas continue to exist after synchronization, allowing you to continue editing and synchronizing the replicas. When creating two-way replicas, the destination must be an ArcSDE geodatabase.
