WordPress&Indexhibit

Hi guys!!
I have my actual website built with www.remarpro.com (home+about+blog). I want to redesign it with indexhibit and keep my blog with wordpress. I have been working on it as local and now want to upload it. My question is how to integrate everything in the server, indexhbit + wordpress. I dont known if I can upload the new design to the same folder as wordpress or I have to move it to other folder and put indexhibit as root folder. How it works??

thank you very much!!!
