Hi, I need some advice for a project I am hoping to start soon.... I am going to be working with a NPO who has a really old website with loads of good content but terrible 1990s design. I will be creating and managing a new ecommerce site and brand for them, which will be hosted separately and have its own domain name. If the new site is successful then I will almost definitely be given the job of rebranding their existing site to bring it into line with the new brand, however in the meantime I will be wanting to copy many of their articles onto the new site. I obviously need to get the new site ranking well in order to succeed, so what is the best way leveraging the authority of the existing content without getting penalised by google for duplicate content if I just copy it?
