I have a file upload script it is written in perl and the version I bought was 1.3 .A newer version the script is now out which I have have gotten from the developers.I do not want to do a complete upgrade as this would erase all custom modifications I have from version 1.3.I need an expert in perl/cgi who can easily understand the script and port features and files(that will be given) from 1.8 to my version of the script used in the production environment.
