We have a Magento multistore with 8 sites. Our database contains about 90 products that are yet Simple products and they use special options because we sell contact lenses that have a lot attributes just like with tshirts in different sizes.
We now want that these Simple products will be converted to Configurable products so we can manage stock/inventory but the products need to keep everything the same as it is now because we have sometimes different product descriptions on some sites but also sometimes different prices , urls, short texts or images.
Some of our sites are [url removed, login to view] , [url removed, login to view] , etc. so you can see how much options some lenses have, this is diffeent per product.
Bid only if you are experienced & professional.
