CYUL2002 AFCAD: please help

Hi friends,can anyone experienced please suggest how do i have to swap CYUL2002 traffic from main airport to its overlay 2YUL?As you can see...CYUL2002-1_CYUL.TXT uses runway 06L/24R for ARR and DEP, and directs the aircrafts to the main ramp, except for the gates 5 to 12 (domestic finger).CYUL2002-2_2YUL.TXT uses runway 06R/24L for ARR and DEP, and directs the aircrafts to the general aviation parkings, and to gates 5 to 12 (domestic finger) of the main ramp....only 2YUL handle GA traffic and so i suppose i have to swap all GA traffic from CYUL to 2YUL. Is that correct? which tool do i have to use for this work? i have AITM but i'm a little afraid...Thanks a lot for any inputcheersLuigi ;-)
