I think the dragons that moved to berk in the first film weren't trained yest but tamed. The only reason dragons attack Vikings naturally is beacause of the Red Death. So now that Red Death is dead, the dragons don't attack Vikings. The trouble that happened in How to Start Your Dragon Achademy was possibly that the Vikings didn't give the dragons enough food as they did at the end of the first film and HTTYD2.
