Our WordPress “Change URL” Plugin
We do a lot of WordPress installs for clients when we set up new websites for them. One hassle we always go through is setting up the development site as a sub-domain or as a complete other domain, and then having to move it to the new domain. Since WordPress uses absolute URLs in posts, links, etc., editing by hand is definitely not an option. We also couldn’t find a really good solution, so I wrote a plugin that will go through all of your posts, pages, options and guids and update your old domain to your new domain!
Directions
Just download the plugin, unzip (if necessary) and install to your wp-content/plugins directory. Activate in your plugin panel inside your WordPress panel. Under Settings is a new option, ‘Change WP URL’. Just follow the instructions!
Download the plugin at WordPress
Download Change WP URL (we’re waiting for WP to approve the plugin so we can get it in the directory)
