Database wp_post insertion

Hi There,

I have just developed a new site for a client on a backup server. I have just migrated the new site to the clients hosting. I created a new database for the newly designed WP site (I realize that developing on the new server would have solved this, but this is how the client wanted it done).

The client has 21 posts from her old blog on the old DB. What is the most acceptable way to move these posts from the old DB to the new one? From what I have read running an SQL query and exporting those 21 post and then adding them to the new DB could cause ID conflicts immediately and in the future.

I realize that with this method I may still have to run through and correct some of the meta-data for images etc also.

Any suggestions would be appreciated, and the solution I’d like to utilize would be the one that is best practice for future development.
