Hide the bottom layer and select the top layer. Apply the Card Wipe effect on top layer from the Effect menu (Effect > Transition > Card Wipe) . Apply the following settings in the image. Don't forget to set the key frame "Transition completion" key frame on 0.5sec at 0% and on 3sec at 100% and same as Rotation Jitter and Position Jitter settings.
