HI Neni.
Rev-Trac is a 3rd party transport management product which amongst other things can make handling large cutovers a lot easier to deal with. The latest version of Rev-Trac includes an ability to simultaneously import multiple transports which is much faster than importing transports individually using a script. It can handle physically separated transport directories automatically.
Rev-Trac can automate all day to day transport migration tasks, is flexible and quick and easy to setup.
