Open one .axmz file and go to [File] – [Compare Project and Merge].
Select another .axmz file.
[Differences] pop-up opens with a list of diagrams and models of both project files in a tree view side-by-side.
Click [Merge] button.
Two merge options will appear. Choose which file to prioritize, and click [OK]. By clicking [OK], all the models that exist only in one file will be merged. If there are the same models in both files but something is different, the ones in a file you chose will prevail.
If you’d like to compare differences
If you’d like to see the difference of diagrams and models in two files, click [Open Compare Diagram] button.
[Merge] does not work for the following diagrams. Ones in you chose at step.5 will stay.

Reset Model ID
All the model elements you create in Astah System Safety will have ID internally – we call this “Model ID”. When you merge files, Astah will look into the Model ID and merge the model elements if they have the same Model ID.
When you clone your .axmz files, the Model ID will not be regenerated so it uses the same ID as the original file. In case you merge a file with another file that was created by closing the original one, you may want to reset Model ID of one file to prevent the unintentional result.
To reset the Model ID, go to [Tools] – [Correct Model] – [Reset All Models’ ID].
Read before you reset Model ID
You cannot [undo] after resetting the Model ID.
We recommend you create a back-up file before you reset Model ID.
