Installing Zen locally?

Hello.
I am using EasyPHP to do developing work locally for my oscommerce store. I am considering a change to Zen. If I install Zen locally, will I have problems with it conflicting with the already installed osc store/db? The change to Zen would probably be a huge undertaking as my current store has over 5k of items, so I need to gather as much info as possible to make an educated decision on whether to proceed with Zen, or stick with OSC.
Thanks for your time.
Tom

As long as zen is installed in its own web directory, and has its own DB, I don't see why you would have any problem.

I always have two distinct installations of Zen running on my own server. I follow the above instructions and have no issues.
