To upgrade a 7.0 model within Rational XDE, you must open your model in Rational XDE version 2003.06.12 or later. When you upgrade models from 7.0 to 7.1, all models (including referenced models) go through a model profile upgrade process that ensures all models use the latest model profile. For detailed information on this process, refer to the following online help topics located within the Rational XDE product information center:
After you upgrade your models to version 7.1, you can import them into one of the Rational UML modeling products. However, after you import your XDE models, you cannot bring the models back into XDE; the model import process is one-way.
