Will new ES2 saves be deleted?

On ES2's release, I know previous savegames were wiped / corrupted. I'm coming back to the game after a long break and understand there's an engine port from Unreal 4 > 5 about to happen or that already happened. Will there be any additional savegame wipes in conjunction with this change or going forward? I don't want to start a new game and then have my progress reset and would rather hold off if that's the case. Thanks in advance. 🙏🏻
