Tag Configuration Synchronization between Tiered Historians

If a summary tag is deleted on the lower-tier historian, its corresponding tag on each next-tier historian remains intact to allow for retrieval of data already collected. A lower-tier tag cannot be deleted from the lower-tier historian if it is being replicated. You must first delete the tag replication and then delete the lower-tier tag.

A next-tier tag can be deleted from the next-tier historian, but it should be deleted only after the corresponding replication has been deleted from the lower-tier historian in that replication relationship. Otherwise, it will be recreated.
