Problems with changing blog from example.com/blog to blog.example.com

[ntsupply]

Currently we have a Wordpress blog on a domain subdirectory ie example.com/blog. We are possibly going to change it to blog.example.com in order to move it off the server for security reasons. I know it benefits the sites SEO as a whole to host the blog on a subdirectory instead of a subdomain, but I am wondering if there is a best way to make this move if we have to?

Any thoughts are welcome.

Make sure to 301 the current page to the new one - as well as the old archived posts to the new post pages (assuming you are keeping the archived content.
