We are currently finishing off a development site dev.example.com for a business who currently have a website that needs updating www.example.com. We want to display all the content from the dev site on the main site's domain but do not want to affect the main website's SEO score.Well when we asked the hosting company to point the main site to the dev site they said there would be a negative SEO impact. The whole URL structure will change and Google will notice 30+ page errors. They suggested replacing the files on the live domain and setup the necessary 301 redirects but not sure what they mean by this entirely
Replace website with newly redesigned and developed site without effecting SEO
