I'm not quite sure how this is done. I want to export a csv with configurable products along with the associated products. Then I would like to import them over on another magento install. How is this done? and is there a way around getting an extension? I have already tried http://www.magelynx.com/checkout/cart/configure/id/1166/ but that didn't work.
I believe you can find the information you need in Magento's user manual:
There should be no need for any 3rd party modules to achieve such.
