a bit more information. Just for clarity's sake, are you recommending 1.0.9 -> 1.0.12 ->
1.1.12 -> 1.2.x? Or would  1.0.9 -> 1.1.12 -> 1.2.x suffice?

from 1.0.X->1.2 will work. You have the best chance at no failures if you go through 1.1.12.
 There are some edge cases that can cause errors if you don't do that.
