Currently I have a Profilux 3.1 set up including doser. All my current settings are saved on my laptop. If I change to Profilux 4 mega set, do I just plug everything into the same slots on the Profilux 4 and new power bar and the download my Profilux 3.1 setting onto the Profilux 4....or do I have to totally reprogram the Profilux 4
