Dean’s Permalink Migration is one of the best way to change WordPress Permalink. The plugin is no longer available in WordPress Plugin Respiratory. Some people claims the plugin do not work but many are fine with the plugin. When we tested the last version of the Permalink Migration plugin, we found it perfect.
To use the plugin you will need to change the permalink structure in your dashboard and then place the old structure here in the plugin settings. After that, You will need to “Permalink Settings” page, again. And flush rewrite rules by simply saving the permalink settings.
For any question or suggestion leave a comment. Go ahead and download the plugin, if you are looking for that.
