Switching from b2 to b7 - prefab references issue

And any news on this one ?

Just to be sure if we have a project entierly commited (Assets/ProjectSettings) on a VCS (git, svn, perforce, …)
If someone checkout this project and open it on Unity 2018.3b8 (for example) all references must stay now and everything must work on the first launch without any reimport after the first full import etc… ?

If the response is “yes” I can say it’s a “no” cause we get again that kind of issue on a fresh project with b8
