I believe the orchestra seating was removed and stadium seating inserted.
I think imperial was redesigned a bit for Natasha, Pierre… to accommodate the table seating in the front similar to roundabout and Henry miller for cabaret.
Shubert theater replaced two aisles with center aisle for Matilda so the front orch was reconfigured.
And circle in the square is reconfigured in the round for several shows like once on this island.
