Can I seed a replication group member with data prior to the initial replication?
Yes. DFS Replication supports copying files to a replication group member before the initial replication. This “prestaging” can dramatically reduce the amount of data replicated during the initial replication. To prestage a replication group member, copy the files to the appropriate folder on the destination server(s), create the replication group, and then choose a primary member. Choose the member that has the most up-to-date files that you want to replicate because the primary member’s content is considered “authoritative.” This means that during initial replication, the primary member’s files will always overwrite other versions of the files on other members of the replication group. For more information about the initial replication, see the TechNet article about what to expect during initial replication (http://go.microsoft.com/fwlink/?LinkId=75044).
