Chapter 17 Migrating from ERwin to PowerDesigner

Preparing to Import your ERwin models

This section provides a list of suggestions for how to prepare your ERwin files and set up your PowerDesigner environment:

• We recommend that you import from an ERwin 4.x file (.xml) rather than a 3.x file (.erx), due to the greater amount of metadata available in the newer ERwin files.
• Review your ERwin model to see if any model object names are duplicated. It is good practice to avoid using duplicate names, and PowerDesigner will automatically attach a suffix to any duplicate objects that it encounters during the import process.
