Steve.. I just looked it up. Here is cut and paste of how to do it. Hope this helps.
How do I transfer my current listings to Auctiva?
Once you have generated your eBay token, your active listings will be automatically copied to your Auctiva account. It typically takes 6-12 hours for all of your active listings to be imported into your Auctiva account and appended with the Auctiva Scrolling Gallery
