Move blog posts over from old site.

Hi,

I am in the process of redesigning my website and have a question what is the best way to transfer over my old blog posts.

Current site – http://welcometobccp.org/blog/
Redesign site – http://1c5.964.myftpupload.com/

I would like to transfer over all the blogs from the current site over to the redesign site. The problem with the blog on the current site is that they are not formatted properly like that redesign site. Is there an easy way to transfer these blogs over into the new format? Please advise.

Thanks
