I started a Blogspot blog several years ago and contributed a few posts to it off and on over the years.

Then I revamped this web site using WordPress and wondered if I could import those few posts into this blog.

After enough Googling and experimentation, I can recommend the plugin SEO Blogger to WordPress using 301 Redirection.  It did a very clean job and I was able to pull over my blog posts, categories and even the comments.
