Blog Time out without SEO hits?

I need to take a time out from my blog—the first time in 14 years—without getting hit by SEO.

My thought was to reprise a dozen of my favorite/most read posts.

But how do I do that without messing up the SEO from those posts?

Could I post them (on my WP blog) and click that box that says “don’t count for SEO?”

Any suggestions would be helpful.

Thanks.
