"Welche Aktivitäten sind dazu notwendig?" vs ""Welche Aktivitäten sind dafür notwendig?""

There has been a discussion regarding which sentence is grammatically correct. So my question is whether they are both correct or not and if they are, is there a difference between the two sentences?

Both sentences seem perfectly fine grammatically and there seems to be enough overlap in the definitions of dazu and dafür to say that both could mean the same thing.

The sentence with dafür is more colloquial, but correct are both :) *native speaker
