Migration from PWB Brand Taxonomy to Product Attribute

Hi,

I’ve been using pwb-brand for about 3 years now. However, now there is a need to have the brand as a product attribute. I’ve close to 1500 products/variation across 40 brands. What would be the best way to:
1. Create brand attribute terms corresponding to each pwb-brand so that we can get name, slug, and description imported. I will add the image manually.
2. Create brand attribute values for each parent product by copying these over from the pwb-brand taxonomy.

I do not want to move the values, rather copy them. This will allow me to use PWB again, as needed.

Thanks!
