I am running M2 version with no problems. I have active users on it and seems to work well.

I want to upgrade to M3 but I am bit scared since the last time I upgraded (M1->M2) it was not smooth, and I had to recreate all the users manually and to import user emails from a backup.

Is upgrade procedure/scripts is a part of M3 release ?

Did anyone upgraded from M2 to M3 ?

Are there any issues that I should be aware of ?

Thanks in advance.
