In addition to the body-swap movies mentioned, this movie bears most resemblance to "Vice Versa" (1988), about a father and son who accidentally switch bodies.
This movie has the same plot of two other films where characters switch bodies: "Freaky Friday" (1976) and "The Change-Up" (2011), although this is a father and son switching bodies; "Freaky Friday" is a mother and daughter, and "The Change-Up" is two friends.
