In WordPress, when you create a main category and create a category as its child, connect some articles to the child category and then open that category, you will see that article in the list of that category. 
So far no problem and everything is working properly. 
Now, if you add a word in the browser address between the main category and the child category, it will still display the same list if that category does not exist and it should be referred to the 404 page.
example.com/parent_category/child_category/ —> post1 , post2 
example.com/parent_category/random_text/child_category/ —->post1 , post2
after install
example.com/parent_category/child_category/ —> post1 , post2 
example.com/parent_category/random_text/child_category/ —> 404
With this plugin, this problem will be solved and a 404 page will be displayed for addresses that do not exist. 
This problem will be very useful for colleagues who work in the field of SEO.

This plugin allows you to select your “From”, and “To” Taxonomies, to convert all terms. Optionally select a parent term to limit terms to switch. Typing term names will do a live search of terms with the name you are typing AND possess child terms.
Plugin also has built-in support for <a href="http://wp-cli.org/" rel="nofollow ugc">WP-CLI</a>. In the command line, type in <code>wp taxonomy-switcher</code> for instructions.
<a href="https://github.com/WebDevStudios/taxonomy-switcher" rel="nofollow ugc">Plugin is on GitHub</a>. Pull Requests and Forks welcome.
<h3>Notes</h3>
Please keep in mind, if parent isn’t set, or you don’t specify a comma-separated list of term ids to migrate, it will migrate all terms for that taxonomy to the new taxonomy.

Taxonomy Switcher

Not sure the forum policy on swearing on here, but this plugin is chuffing amazing, saved my bottom recently as I imported ~7000 term into the wrong taxonomy, and it transferred it over no fuss.

This saved my bottom!

Don't let the small number of active installs fool you: This tool does what it says and does it well. Once the data is modified, most people (like myself) probably uninstall it.

Kudos to the Authors!

Awesome Tool!

Does exactly what it claims to do and works flawlessly. Thanks!!

Awesome!


I started using this plugin recentlyThanks for the CLI support



Works as expected


Kudos to CLI support

Switch the taxonomy for all terms or only child terms of a specified parent term.
