Instructions provided describe how to create a replica, when the coordinate systems of the data in the parent and child geodatabases are different.
This workflow is not supported for Geometric Network data because projected Geometric Networks cannot be edited.
Before creating the replica, extract the data to the target (child) geodatabase. This initial data extraction must be done separately from the replication, because a few extra procedures are required to get the data into a different coordinate system.
It is a good idea to specify the datum transformation to have applied to the data if, for example, the origin and destination coordinate systems are based on different datums. The data extraction process in Step 4 automatically applies any transformations set. Unless specified, this transformation is not automatically applied because many or no possibilities may exist.
Data extraction preserves Global ID values. Replication uses Global IDs to identify the same feature/record across databases, so the values must be consistent across the geodatabases.
Make sure that the data on the child geodatabase has no records before performing this step. This will be the case, if Step 2 has been performed.
