help conversion question

I have been given the task of updating a certain model done for the
county. It used SWMM Version 4.4GU, needless to say none of our
machines have this version of the software anymore. I currently have
version 10.07 installed on my computer.

So my question is can i convert a version 4.4GU to a 10.07?

Please let me know if you can help.
