Advice for building a dev / production server pair

Hi,

I'm interested in building two Linodes with Ubuntu 12.04 LTS. One for dev, one for production (LAMP, Wordpress).

I'm guessing I could get there by building/configuring the dev Linode first, then to build the production Linode, somehow copy the dev Linode's image onto a second Linode, adjust that Linode's Virtual Host (and whatever else I'm forgetting that should change) and done.

Am I in the ballpark? Anybody 1) know what the steps with the imaging would be and 2) have any suggestions concerning the process?

Thanks,
