Merging Models

You can merge the content of two PowerDesigner models or two resource files of the same type at any time.

Note: For information about selecting resource files to merge, see "Merging resource files" in the Resource Files and the Public Metamodel chapter of the Customizing and Extending PowerDesigner manual.
  1. Select Tools > Merge Models to open the Select Models to Merge dialog box.

    The current model is displayed in the To field.

  2. Select a model to merge in the From list. Only models of the same type in the workspace are available for merging.

    Note:

    If you want to merge two PDMs, BPMs, OOMs or XSMs, you have to select two models with the same target DBMS or language

  3. [optional] Click the Options button to open the Comparison Options window and specify which objects and properties you want to include in the comparison and possible merging (see Comparison options).
  4. Click OK to open the Merge Models window, which displays the objects contained within the models or resource files in a tree format, and highlights the differences between them (see Analyzing Differences in the Merge Models Window). You can apply a filter to simplify the list of differences (see Filtering the Changes to Merge).
  5. After selecting the merge actions that you want to perform, click OK.

    The Merge Models dialog box closes and the merge begins. Merge messages are displayed in the Output pane. A final message informs you that the models were successfully merged.
