You’re talking about Big Bang Two. From what I read it did reboot the Universe but the actions of the previous Doctors still took place. A wiki article mentioned an episode of the Sarah Jane Adventures that happened after the reboot stating actions from previous Doctors. Plus, River’s journal had it’s contents returned. And from the latest season, we know River still ends up in the Library so she met the 10th Doctor. My question is, do humans, institutions like Torchwood and UNIT still know about the Doctor and Aliens during the first episode of the 11th Doctor when he is looking for Prisoner Zero and does Amy Pond know about the events of the 10th Doctor (Cybermen, Daleks, etc)? That episode was before the Big Bang.
