Moving content from site with no traffic to a new site

Hello,
I have seen similar posts to my question, but my situation is a little different so thanks in advance for bearing with me!

I put up a site 5-6 months ago, wrote a handful of posts (less than 10), then abandoned it. The site has gotten pretty much zero traffic except for a couple google pings. I’ve decided that I want to move that content to another (new) site, delete it from the original/old site and use the original/old site for something else entirely. I know I could use the export/import tool to move the handful of posts to the new site, but my question is do I need to even bother to set up redirects from the old site?

I also probably won’t get to re-purposing the old site for awhile, so essentially I could temporarily shut it down, if that’s possible. Basically, I’m just looking for the easiest way to move the content & (eventually) repurpose the old site without doing anything that looks like plagiarism to google.
