How do they change the Oakland stadium from a football field to a baseball field?

The Oakland Raiders play their home games at the Oakland Coliseum which is also home to the Oakland Athletics major league Baseball team. The Coliseum is not a baseball field, it's a multiuse stadium, which is used for both football and baseball when these seasons overlap (September to early October, unless of course, the A's make the playoffs). Once the baseball season is over they will fill in the dirt basepaths with sod and it will look more like a football field then.
