Creating a model element identifier database

You can create a model element identifier database from a migrated Eclipse Modeling Framework (EMF) model. You use the database to align migrated models that you want to compare, merge, or combine. You can create multiple databases at one time. Each database is generated from one model file.
About this task
To create model element identifier databases:
  1. In the Model ID Alignment view, from the Operation list, select Create ID mapping files from initial set of models.
  2. Click Add Files and browse to the location of your model files. Select one or more model files. Each model file that you add is used to create a separate database.
  3. To check if any of your models have elements with the same identifier, click Check Duplicate IDs.
  4. To select a different location to resave your initial set of model files, in the Save Location of Models with aligned IDs area, specify the location.
  5. To change the output location of the generated model element identifier databases, click Browse and specify a new folder location.
  6. Click Generate ID Mapping files.
