Yeah, they did exist before DC vs. Marvel (such as Superman vs. Amazing Spider-Man Vol 1 1) but those crossovers weren't canon to New Earth (or Earth-One for the comics of that era). In DC Versus Marvel, weren't they unfamiliar with the characters from the other universe? Did they remember the previous crossovers? If not, then they didn't meet in New Earth until DC vs. Marvel. They met in Elseworlds stories.
