as said i started modelling flows, processes, project systems etc. with ecoinvent 3.5 and i'd like to update my work to the current ecoinvent 3.7 version. Is the a way to port my work from my existing database with ecoinvent 3.5 to a new database with ecoinvent 3.7? Simple copy&paste or drag&drop didn't work for me. Or do i have to remodel all the created elements in the new 3.7 database?

Hi, good question; in principle the UUIDs for the processes are the same in different versions, but the migration requires some more details to work perfectly. We plan to prepare a script for the version 3.8 to help migrating from 3.7/3.7.1.

For now, you can export only your foreground system as JSON-LD, and then import this into 3.7, select overwrite as option, and then check your model.

Best wishes

Thanks for the answer. So in theory it should work but no guaranty for success?

I tried following your instruction but i didn't succeed. Did i miss something or was this a case of "some more details" not working perfectly.  
I did right klick and export on my database, selected JSON-LD export wizard and marked the folders with my created flows, processes and product systems. Exporting was no problem but the import was. I cancelled the import process after it ran for several hours with no progress and no foreseeable end.

Could you please add more detail to your instructions?
