I am working on the theme where I have converted "form based" cart to "AJAX" cart. And in that I add two specific properties to all the line_items.
Now my issue is, when I go live with this altered theme, what to do with existing carts. Means all the existing carts where there are some items already added to the cart without any properties, and I can not have such items in the cart.
Is there any way I can delete all the carts using some api or so....
