Freedom Permalinks can help you to change permalinks to any format you want. 
Update slug structure, change domains, remove/add slashes or add extensions (.html, .php or anything you want) etc.
<pre><code>PS. While this gives you freedom to play with permalinks, you should know that you have to make those link structures work with your themes yourself.
</code></pre>
For example if your theme is installed on subdomain1.domain.com, changing permalink to subdomain2.domain.com will break the existing links and you have to move your theme manually to subdomain2.domain.com to make it work.
<pre><code>Things you must know before trying this plugin:
1. It's best suited for custom/smaller themes.
2. Always create backup of your database before trying this plugin.
