Migrating modeling resources from previous version

In the previous version of the Rational® UML modeling products, the UML modeling resources are based upon the UML 2.0 metamodel. Auto-migration has been provided to convert the previous profiles, models and diagram files into their equivalents, but there is no support for saving these resources back into the previous format.

Before you begin

When a previous version of a modeling resource is opened, the Rational modeling products will detect the older version and automatically perform the migration in memory. If the user does not save the model, the format of the corresponding resource on disk will remain in the previous version. When the user saves the model, the resource on disk is written in the newest version.

Note: Once a profile, model or diagram resource has been migrated to this version and saved, the previous versions of the Rational products will no longer be able to open those resources.

About this task

The version 7 of the Rational modeling products support the same mechanisms as the version 6 products for registering profiles, so that the profile can be resolved when it is applied to a model. One registration technique is to use a PATHMAP variable to define the location of the profile. If PATHMAP variables were used in version 6 of the Rational modeling products, the PATHMAP variable names in version 7 must be identical. Another profile registration technique is to keep the profile in a project in the workspace. If this technique was used before, then the corresponding project name and profile pathname in that project must be identical in version 7.
