Well, i did upgraded all the way up to 4.10, without uninstalling. 
And yes, correct, if you upgraded from 4.6-4.7 to 4.9. then you had DB error, that should be fixed now. 
But i still advice the step 4.8, why, just because i know that works fine.

Yes, just make user you smb.conf is correct and adjusted for 4.8 ... 
BEFORE you upgrade, that will save you some hassle. 
This applies for every major upgrade as in 4.5 to 4.6 or 4.8 to 4.9 ..
Any 4.x. to other 4.x.

And ... Brrr.. Italy was much better weather..  I went from 32c to 15c.. 
But i was good.. 

Greetz,
