That’s why DC’s had so many continuity problems since the first Crisis event.
1986 - Superman, John Byrne, Wonder Woman, George Perez.
Superman, a most notable instance for DC's most iconic hero / franchise, everything started over again. Re-updated his origins in Krypton, Smallville, Metropolis. Jonathan and Martha Kent living through Clark's Supermandom. Lex Luthor CEO of Lexcorp. Restarting relationship with Lois Lane. And gradually battling many of his enemies again. And it still took years before "classic" incarnation of characters like Bizarro Superman, Supergirl, Krypto, and Brainiac, became re-depicted again.
To my knowledge, the only remainder slips of Pre-Crisis Superman that processed Post-Crisis, was Darkseid remembering Pre-Crisis Parasite, which led to Post-Crisis Parasite, and a couple of Fourth Walls in Animal Man. But, other than that, everything Superman started over again, and built from there.
