Converting an extremely old ERDesigner file (xdm) to latest so I can open it. #299

Closed ChristianSHansen closed 2 weeks ago

ChristianSHansen commented 3 weeks ago

Any help would be greatly appreciated. I have an extremely old Mogwai ERDesigner file with the extension of xdm. I would really like to be able to open it in the latest version of the software. Any steps that I should take or what I need to edit in the file so it will open? Help!

Hi @ChristianSHansen,

are you allowed to share this file? It should be convertible, but I also have to take a look at the file structure again, to give a good explanation. Maybe the best way could be to generate a database schema from it and do a reverse engineering to get a valid ERDesigner NG model from it...

Hi, I will take a look at it!

In the meantime you can try to get the old version running by downloading ERDesigner at https://sourceforge.net/projects/mogwai/files/No%20longer%20supported/Mogwai%20ER-Designer/.

Your file seems to be created with Release 0.9.8, wich was released in 2005 :-). Be aware that you'll need a Java 1.5 or Java 1.6 runtime to get it working. Maybe it will run with 1.8, but I am not sure and havent't tried.

If this software works you can create the database schema with ERDesigner 0.9.8 in a database and use ERDesigner NG or any other ERD tool of your choice to convert it back to a model.
