Thank you for suggesting this change. I just wonder why we don't have changes arround the DataMigration.ts nor in data.service.ts

When i am loading a Netzgrafik using the numberOfStops the data must be migrated into the new schema - right?

See data.service.ts

  loadNetzgrafikDto(netzgrafikDto: NetzgrafikDto, preview = false) {
    this.netzgrafikLoadedInfoSubject.next(new NetzgrafikLoadedInfo(true, preview));

    DataMigration.migrateNetzgrafikDto(netzgrafikDto);
    
    ...

Yes it's true. This change will occur at the end of the development of the new nodes management system.
@louisgreiner just report the implementation plan in this issue. (it will be translate soon).
Before permanently removing the nbOfStops property, we will modify the loading script to transform nbOfStops into an actual Node. This will allow us to not break existing projects and remain consistent.
