Same content on site blog as a separate blog. Will unpublishing on one blog evade duplicate content issues?

I just discovered my client was posting the same content as the site I'm working on for him on a separate blog. I don't want to run into duplicate content issues. Both are Wordpress sites. Will it suffice to simply unpublish duplicate entries on the other blog and leave the posts as drafts?

Deleting the duplicate posts works. If the post has to be kept in two places you could use rel="canonical" tag to let Google know which is the original version.
