I am in the process of migrating from an older Magento 1.7 to a Magento 2.1.5 webshop.
On the new one, after a very tricky database migration I have a weird occurrence of some products being on sale, that weren't on sale in the old webshop.
See the below links for examples, the first link is to the older webshop where the products are shown with the correct price, the second link is to the new shop where the products have been put on sale.
Now I have no listings in my Catalog Price rules and Cart Price rules on my new shop, I though maybe it would be here that these sale prices are being set but it does not seem like it.
On the old shop, there are some Catalog Price Rules, so I'm thinking that during the migration of the product database might have brought some sale settings with it, I only wanted to migrate the product catalog, not sales history etc.
Could it be in the database where I will find the reason why these items that are being put on sale? I do have phpMyAdmin access and can edit the database directly if needed.
