Advice needed - Transfering domain content to another

[joey99999]

Hi,

Just wanted to understand how Google works in this particular case. I have a site which is expiring soon and i do no intend to renew. I have very good content on online niche marketing which i intend to transfer over to my business blog (giving a broader perspective).

How do i do that without infringing duplicate content? I understand that duplicate content is ok for using others' articles to blogs. But what about same or adapted content from blog to blog, especially when both are your own?

Thanks a mil for the advice in advance

Joey
