Capella Project migration

Hello everyone!
I tried to migrate a Capella project from 0.8.3 to 1.1.0. The project is a melody project (so I’ve got 2 folders : “.aird” and “.melodymodeller”).
Following the migration link tutorial, i’ve got an error message… "Problem Occured : org.eclipse.emf.ecore.xml.type.impl.AnyImpl cannot be cast to tyType. "
the “.old” files are well created but I can’t open the new files…
Could anyone help me?
If you need more information, don’t hesitate!
Thanks for your help!

I’m not sure if migration works if you jump a release. Did you try to migrate from 0.8.3 to 1.0.0 and then from 1.0.0 to 1.1.0.

thanks for your answer!
I will try and let you know

Edit :
I downloaded the 1.0.2 Capella version. I follow the migration steps.
I’ve tried now and here is the result :

  • no error message
  • impossible to open the MelodyModeller as I could before… (see linked files).
    is it normal?

Ususally you don’t open the melodymodeller file, but the .aird file.
