Chapter 16 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.
