Maintaining Implementation Structure

With the default operational rules preloaded in the CA Gen schema tables, the implementation structure (IMPUSE objects, associations) from the SOURCE must be maintained in the DESTINATION or the migration fail.

• If the triggers have not been generated, this implementation structure does not exist, and migration completes successfully.
• If the triggers have been generated in the SOURCE, the IMPUSE objects and their associations are migrated as components. All triggers directly associated with the one being migrated must exist in the DESTINATION, or else migration fails.
• If the triggers have been generated in the DESTINATION, and they do not correspond to those from the SOURCE, they are flagged for the deletion during migration processing. Unless all associated triggers are deleted, the migration fails.
• Enforcing the SOURCE model implementation structure for RI triggers is appropriate when all models participating in migration of data objects have equivalent entity relationship diagrams and technical designs.
