With brand new I meant without me messing with it. 
I used 221215 for my test database. I tried to restore on this one and also on 250216.
I got a bit further on 25016 but i get error “ImportError: no module named formis” after migrating. – I had a custom app “formis” with two doctypes on my testing machine. If you have any Ideas please tell me correct steps how to restore my database to a new machine.
Thanks
