What to consider when comparing with an imported BPMN 2.0 diagram?

When comparing an imported BPMN 2.0 diagram with a BPMN 2.0 diagram that already exists in ARIS, choose the Any model option on the first page of the Model comparison Wizard.

When the comparison models are opened, enable the Compare tab and click Model comparison options. Enable the options depicted below.

Model comparison options

Under Additional criteria for identifying identical objects, activate Objects with identical attribute and select External ID (no copy) [AT_EXTERNAL_ID]. If you import a BPMN file that was exported earlier, you must export the BPMN diagram in ARIS Architect and reimport it to be sure that the External ID (no copy) [AT_EXTERNAL_ID] attribute is set and you can compare the two BPMN diagrams.

In the model comparison view, clicking in the Details pane on an element will also select the counterpart in the other model and a menu below will show the difference between them.

If you want a detailed report of all changes, click Export all differences in the model comparison view to create an XLS file with all differences in detail.
