This plugin updates all URLs in the database after moving your site from one domain to another. It is useful for switching between development, testing and production stages.
Why this plugin ? WordPress stores absolute URLs in :
<ul>
<li>posts (including pages and custom post types), drafts</li>
<li>excerpts</li>
<li>medias</li>
<li>custom fields</li>
<li>options (including ‘siteurl’ and ‘home’, in wp_options table)</li>
<li>GUIDs (only for development)</li>
</ul>
When moving your website to a new domain, all these links will point to your old domain name and become outdated.
<h3>Prerequisite</h3>
Before moving the website, consider making a backup of the database. Then, once the site has been moved, you will need to manually update ‘siteurl’ in the ‘wp_options’ table, in order to access the WordPress Administration panel.
