Working in a simple development environment

Existing version 6 modeling projects can be imported into the version 7 Rational UML modeling products. If all of the members on a team are migrating simultaneously to version 7, and the modeling resources no longer need to be opened in a version 6 environment, then the migration steps are quite easy.

Migrating UML profiles

If there are UML models that have custom profiles applied to them, the profiles must be migrated first. After the profile is migrated, the profile must be registered in version 7 of the Rational modeling product in the same way as it was in version 6, so that models will be able to resolve the applied profile reference.

To migrate the profile, open the profile in the version 7 workspace. When the profile is opened, there may be a prompt to update ProfileBase to the latest version. If so, click Yes and the profile will be "dirty". If not, simply toggle the visibility (change visibility to private and back to public) for one of the stereotypes to dirty the profile. Save the dirty profile to create a 7.0 version. In the Project Explorer view, right-click the root profile element and in the context menu, click Release, and enter an applicable label.

Migrating UML models

After all of the required profiles have been migrated and registered accordingly in version 7, the models can be migrated by opening the models in version 7. When prompted, all profiles applied to the model should be updated to the latest version. In version 6, there were three base UML profiles (Basic, Intermediate and Complete). In version 7, these profiles have been combined into a single Standard profile. When the model is saved, it can only be used in a 7.0 version of the Rational modeling products.

Migrating diagrams

The migration of the diagram (.dnx) resources from version 6 to version 7 is performed automatically when the diagram resource is opened for the first time in version 7; however, there is no support for saving a diagram resource back in the version 6 format. Once the diagram is saved, it can only be used in a version 7 of the Rational modeling products.
