I imported a client's products to a brand new website (which has now just been moved to the previous URL). I went through them all and updated SEO, attributes, stock level, etc.
Now that I have moved the new completed website to the existing URL (replacing the old site) all of the product listings from the old shop are showing up on the website shop page, not the new versions that I spent hours tidying up.
The backend shows duplication of all products. Duplications were not showing before the move.
I tried deleting the old versions of each product, which resulted in no products showing in the store at all.
How can I make the store pick up the new version of each product listing, so that I can delete the old versions?
