There's no way you can have two instances of Zen Cart in one root folder. Just like trying to park two tanks in the same parking space!
Two carts in one directory would require two admin/includes/cofigure.php (for starters) or one

of a lot of coding. Last time I looked, even windows can't get two files with different settings to occupy one filename.
Don't know how GoneDaddy loaded your files, but, if you don't have an install directory, you won't be able to upgrade the old database when you're done upgrading. This generally happens with a Fantastico load.
You may need to get a little more involved in the process than pouring the cheerios in the bowl and adding milk
You're going to need to separate the cheerios from the honey-nut cheerios and see what needs to be put in the bowl from the old cheerios bowl.
