Upgrading to CA ERwin Data Modeler r8

Models

You can upgrade any model from r7.x to r8. However, if you participated in the beta program and either upgraded any r7.x models to r8, or created any r8 models using beta software, you will be unable to open or upgrade those models using the GA version of r8. You must re-upgrade your r7.x models to r8.

During the r8 upgrade process for CA ERwin Data Modeler Workgroup Edition, a dialog opens if you have any models that are stored in a r7.x mart that are Version 4.x. This dialog contains a list of all the Version 4.x models and presents you with the following options for each model:

• Delete the Version 4.x model and continue with the mart upgrade.
• Cancel the mart upgrade. Doing so lets you go back to CA ERwin Data Modeler r7.x, convert the models from Version 4.x to r7.x, and save to the mart. After you have saved these models to your mart you can continue with the r7.x to r8 upgrade.

Printer settings and paper size considerations

If you use a paper size other than Letter, before you upgrade any r7.x models to r8, ensure your paper size specifications are set in the Printer Properties dialog and saved with the model. Otherwise, you must reset your paper size in the Page Setup Editor in r8.

Deleting subject areas during the upgrade process

The r8 upgrade process includes the option to delete the Main Subject Area. When the upgrade process completes, the model opens in r8. If this model contains other subject areas that you want to delete, then for better model performance we recommend that you first save the open model and close it. Reopen the model and then delete any subject areas that you want to remove.
