They have announced the conference opponents/sites for 2024 and 2025.
Iowa will play at home vs Maryland, Nebraska, UCLA, and Wisconsin and play at Illinois, Minnesota, Ohio State, Rutgers, and USC in 2024
Iowa will play at home vs Michigan, Michigan State, Minnesota, Northwestern, and Penn State and play at Indiana, Nebraska, Purdue, and Wisconsin in 2025
So Iowa will have to play Michigan, Ohio State, Penn State, and USC in the next 2 years. That’s a much more difficult change to their schedule vs what they have been used to for the last 10 or so years
