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.
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.
