How can I move/redirect single blog posts from one blog to another?

I see lots of answers about moving entire blogs, but here’s my scenario:

I have a few blogs with a lot of content. I’m no longer publishing new content on these sites. I’m now publishing on another (new) site. I don’t want to migrate all of the content from the previous sites, but I’d like to move a few “greatest hits” posts. What’s the best way to migrate a few single posts from one site to another?

I’m thinking that for SEO purposes, it would make sense to have a redirect in place so that the posts currently receiving search traffic will pass that traffic onto the new site.

The best way of doing that is actually by just copying the post to your new blog, and on your old blog, add a rel=”canonical” link to that page to your new post’s URL. This will notify Google and other SE’s that you want to have the other, new, page ranking, without actually having to annoy your users.

There are several plugins that can do canonical, two of them are mine, if you’re not doing a lot of work on those old sites i’d recommend using my canonical plugin.
