I think since the beginning of next year will not be released. The delay is not only because application release, it is also because must prepare all the documentation, check everything etc..
In July-August we have done a lot of advances on it, but since september the load of work returned again and the speed of changes decreased
No, will not be easy. It will be harder because the database changes and does not have a direct migration. It will be a process and a guide for doing it. Probably with some video.
