So I would like to know the most optimal way how I can merge my existing simple products (let's say 1 product, in 5 different colors, so 5 simple product pages) to 1 configurable product. I would also like these swatches to have mini thumbnails of the product in the other color. Could this be achieved through an extension/module?
Also, we're already using Amasty Color Swatches Pro, but to us it's not sufficiently efficient enough, since you need to add every existing color to an attribute, then you need to assign this attribute to all respective simple product pages, then you need to create a configurable product and add them as associated products.
I would love to know another approach or module on how to easily add/merge my simple products catalog (over 3800 products) together into configurable products.
