I'd suggest handling this the same way, more or less, that the DC Database fandom Wiki does in regards to the pre-Flashpoint and post-Flashpoint characters they cover, even if the characters' histories are near-identical in both their "pre-Crisis" and "post-Crisis" iterations.

For example, you would have an article labeled "Barry Allen (Earth-1)" that chronicles the character's history up until the Crisis event, as well as an article labeled "Barry Allen (Earth-Prime)" that covers the character's history both before and after the Crisis as the latter history evolves.

The two articles might share much of the same information, but only the second article would be consistently updated.
