Good morning.
I have a blog running Wordpress 2.7 and want to change the theme. Now since I own the server where the blog is hosted and in order to play it safe, I decided to export the blog and import it under a different domain so as to experiment with the new theme on the non-important domain and when happy copy everything to the official one.
My question is: after I am happy with the new theme on the non-official domain, do I have to go through the UPGRADE process documented at http://codex.wordpress.org/Upgrading_WordPress or I can simply copy the files from one place to another and then run wp-admin/upgrade.php?
Thank you.
