Before you import Rational® XDE models into one of the new Rational UML modeling products, you must verify that all models are based on model version 7.1. If your model is based on model version 7.0, you must upgrade the model to version 7.1 within Rational XDE.
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.
