What would be the easiest way to copy all products (including images) and categories from one installation of Magento to another one (completely empty and vanilla) on the same server? I don't need to keep orders, users, etc. but only the products. I don't mind, however, copying these too. I also don't need them to keep the same keys, as long as the association with the appropriate categories stays the same.
Exporting to CSV and importing seems particularly messy, while just duplicating the database simply won't work...
