If you have ever had to move your site from one location to another you know how painful it is to go back and rewrite every link and URL to point to the new location. The Velvet Blues Plugin for WordPress will do exactly that. It allows you to input your new website URL and then it automatically updates every link in your blog.
To get started, first you want to download the Velvet Blues Plugin. Once you have activated it go to the settings tab in your admin panel and select “update URLs”. You will then be shown a screen that allows you to type in your old website URL as well as your new website URL.
Choose which URLs you would like to have updated and as soon as you press update URLs all of the links in your site that you selected will be modified. Although this saves a lot of time, you will still have to go back and manually change any links that are hardcoded. This is by far the easiest and effective solution that we know of that allows you to update your post URLs in WordPress when switching sites.
