Two objects in different models shares common ancestry within a model family if the objects have the same Original Object ID. When a new object is initially uploaded from the toolset, it is assigned a unique identifier as its Current Object ID and this same identifier as its Original Object ID. This identifier is used internally to identify the object regardless of any changes that are made to it, including name changes. When a new object is created through migration, that object is assigned a unique Current Object ID but inherits the Original Object ID from the object on which it was based.
You can determine an object's Original Object ID by using the WalkEncy utility for that object and examining the ORG_ID column.
Migration propagates common ancestry. Consider an object that is created in Model 1, then migrated to Model 2, then migrated to Model 3. The following table defines the object's Original Object ID and current object ID after each migration:
|
