I have an old magento store (1.6.20) that is going to be migrated. Need to remove some categories AND products that are only in that category. For example:
product hammer is in tools, metal and woodworking
product nails is in metal
Remove metal and woodworking, keep tools (and hammer).
Found a script that removes categories + products, but also products inside multiple categories: https://oldwildissue.wordpress.com/2011/11/21/delete-all-the-products-in-a-given-category-via-php/
Can't delete products manually, as there are thousands, most likely they're in multiple categories.
Any hints on how to proceed?
