Migration Replaces Object When Special Equivalency Rule Applies

The following pair of figures provide a before and after view of migration of an aggregate object, where an object in the destination model is equivalent to the object being migrated based on Special Equivalency Rules.

• Different Objects Before Migration—Special Equivalency Rules Apply shows two aggregate objects, the data tables named CLIENT, that are equivalent based on Special Equivalency Rules.
• Same Objects After Migration—Migration Creates Common Ancestry illustrates that when such an object is migrated, migration creates common ancestry between the two objects that had previously been considered equivalent based on Special Equivalency Rules. That is, after migration, the data table CLIENT in the destination model has common ancestry with the data table CLIENT in the source model.
