what toolboxes do i need to run my code

hi

 is there any way to tell what toolboxes i need to run a script. The script is quite large with nested VIs running on an old version of labview (2007) with all the toolboxes installed. We are looking to upgrade labview but obviously we dont want to purchase a load of toolboxes we dont need. Any idea how i can tell which ones are needed to run the script?
