Traditional Migration Approach Cons Remodeling Approach Pros

Requires technical knowledge of all tables and usage inthe E-Business Suite.

Repeatable results, reusable as requirements change. Asrequirements change, only need to add/change rules, astep that is usually done by a functional user on aspecially designed user interface in the software In a veryshort time.

APIs do not exist for all tables. There is a risk ofcompromising the data integrity by extracting and loading

data incorrectly. Oracle Support not available.

All data integrity is maintained because the code isautomatically generated.

..

History is generally not converted. Generally a sunsetinstance is required for reporting, reconciliation, businessintelligence, and audits. Every time the sunset instance isaccessed, data must be transformed to align with the R12instance.

All history is converted so there is no need to maintain asunset instance for reporting, reconciliation, etc. All thedata is complete and consistent.

Need to configure R12 instance No need to configure R12 instance

Scripts are written for the current state of the data. Anychanges require re-writing of the scripts.
