Configuration of Plesk Server/QuickForm

We have an older server which houses a number of websites that utilise the HTML Quickform component (Pear I think). I would like to clone these sites onto our central server and close this down, however we need to have the component installed and tested prior to doing this to ensure the integrity of the form validation/processing is fully functional. This shouldn't be more than an hours' work for a decent sys admin guru!
