It's a harsh question for DC in general, and now it also applies to the Arrowverse. Ultimately, for the sake of posterity, I believe we should make new Prime-Earth versions of various characters, since their past and present has been radically altered, even if some memories still remain. For the sake of my argument, I'd like to present you Bruce Wayne, the Batman, one of the oldest heroes of the DC multiverse. Even in the current comics by Tom King, Scott Snyder, James Tynion, Bruce himself references events that he is not supposed to remember, including those that happened on pre-crisis version of Earth-2. How does he do that, Bruce himself isn't entirely certain and tries not to question it. He keeps a book on "strange cases" that are not supposed to fit in his current timeline. He remembers events differently from other characters. Everything is done to show the connection to the old iterations of the character. Yet, despite those connections, the character has a quite altered history in the new universe. And so, DC Database has various articles for Batman (New Earth), Batman (Prime Earth) etc. (even though the premise of both Flashpoint and Rebirth indicated that New/Prime Earth is the same universe, just fundamentally altered). I consider it prudent making new Prime Earth articles for everybody, but having a link at the top (maybe a small template that isn't too intrusive) that provides a link to the character's pre-Crisis history on their specific Earth.
