If you want to transfer your model to another database the JSON-LD format is recommended.
The EuGeos IA database is based on ecoinvent 3.2 indeed.
And you can change the locations using a Python script or SQL query, but if you are unfamilar with either SQL or Python I would not recommend that. If you have a database backup, an idea is to start from there. You can also contact me directly if you think this is useful.
