Duplicate content from another site, how to make it possible to promote?

Question

Search Engine Optimization

In general, there is an old old site, there is no access to it, but there is content that I duplicated on a new site with a new design, and a different domain. This, as I understand it, is bad for further advancement, what is the best thing to do in this case? Is it possible to continue to promote (not yet started) through direct, etc.??
Thank you)

Answer 1

It is necessary to look specifically at what volumes there are on both sites. Links are better to bribe to a new site. You can try changing the text. And there is also no access to the domain of the old site? (ns change and all that)
