Welcome to the Q&A Forum

Hey guys, I'm new to SEO and have the following error msg 'Duplicate Page Content'. Of course I know what it means, but my question is how do you delete the old pages that has duplicate content? I use to run my website through Joomla! but have since moved to Shopify. I see that the duplicated site content is still from the old Joomla! site and I would like to learn how to delete this content (or best practice in this situation). Any advice would be very helpful! Cheers, Peter
