I have an existing website on the domain root, and when I tried to install ZenCart through my web hosting (Lunarpages) I was told I can't because of exisiting directory. I still need the website to be up and running while I try to figure out ZenCart (since I have no idea how ZenCart will look and how I can customize it to fit my needs) before I fully switch from plain HTML to ZenCart. My question is....

1) Is there a way I can install ZenCart in a different directory and try to figure it out there, and when I'm done to transfer the entire site from the testing directory to the domain root?

2) If not, what can I do aside from shutting down the website?

Thanks!!
