Here's my situation:
I have a website that I'm going to be shutting down within the next few days.
I'm then going to be starting a completely new website (ie, completely new domain name).
I want to take some of the blog posts that existed on the first website and post them onto my new website when it's up and running.
Will search engines look at that as duplicate content? Do blog posts on deleted websites remain in the web's cache for a period of time?
What would be the best way to approach this?
Thank you in advance.
