You can determine the release version of Rational® XDE by using the Rational Software Installed Product Information window. Use this information to determine whether you need to upgrade your models before importing them.
You can only import XDE models created in specific release versions of Rational XDE. Models created, or opened with Rational XDE Version 2003.06.12 or later can be imported into one of the new Rational modeling products. If your model was created in a previous version, you must upgrade the model in a supported release version of Rational XDE.
