<p>Backwards Compatible Permalinks helps prevent 404 errors when switching between permalink structures.</p>
<p>It achieves this by appending a set of backwards compatible post rewrite rules. This ensures posts are still accessible at their previous permalink after the permalink structure is updated.</p>
<h4>Example</h4>
<p>Let’s say your permalink structure is set to “Month and name” and you have a post titled “I Love WordPress.” That particular post would live at <code>https://example.com/2019/03/i-love-wordpress/</code>.</p>
<p>But what if you wanted to switch to the “Post name” permalink structure and have your post live at <code>https://example.com/i-love-wordpress/</code> instead?</p>
<p>You could but this would result in the existing post permalink 404ing when visited. Which is problematic if the previous URL was bookmarked or shared on social media.</p>
<p>With Backwards Compatible Permalinks installed your post would be accessible at both the old and new permalink structures:</p>
<ul>
<li><code>https://example.com/2019/03/i-love-wordpress/</code></li>
<li><code>https://example.com/i-love-wordpress/</code></li>
</ul>
<h4>Caveats</h4>
<ul>
<li>This plugin does not work retroactively. i.e. you must have the plugin installed and activated prior to switching permalink structures before backwards compatibility will work.</li>
<li>Currently only standard posts are supported.</li>
<li>Backwards compatibility is not supported between certain permalink structure updates. This is due to a clash between permalink structure regex matching.</li>
<li>Backwards compatibility is only provided between the most recent permalink structure update. i.e. you cannot change your permalink structure 3 times and have backwards compatibility across all 3 structures.</li>
</ul>
<h4>Deactivate or uninstall</h4>
<p>After deactivating or uninstalling this plugin please ensure you visit Settings > Permalinks in the WordPress admin area to flush your rewrite rules.</p>
