At this point in the WordPress migration class, we've migrated our WordPress Database and our WordPress Application Files. The next step we need to do is update our WordPress configuration file so that the application files can communicate with the database to make your site come alive. Again, this is not as hard as it sounds.

Earlier, we asked that you use the MySQL Database Wizard to create a database, create a database user, and assign that user to the database with all privileges. We also asked that you write this information down as it would be needed later.

How to open the WordPress configuration file - wp-config.php

The following steps will take you through updating your WordPress Configuration file:

1. Log into your Web Hosting Hub cPanel
2. Click the "File Manager" icon.
   
3. Choose "Web Root", "Show Hidden Files", and then click Go.
4. In the right window, navigate to the folder that contains your WordPress files.
5. Find the file named wp-config.php, right click it, and choose "Edit". If you're asked about the character encoding to use, choose "ISO-8859-1" and then click "Edit".

How to Edit wp-config.php

In our previous example, we created the following MySQL credentials:

• database name: whhsup5_wpress
• database username: whhsup5_wpuser
• database password: passwordgoeshere

Our cPanel username is whhsup5, and as you can see from the above cPanel automatically adds this prefix to all database names and usernames.

The database credentials that WordPress uses to connect to your database are contained within the wp-config file. What we'll need to do is find the files and simply change them. Start off by finding this section within the wp-config.php file:

Take a look carefully at the above code, and you should see that this file is define what the database name, username, and password are. The value 'localhost' is very commonly defined as the host, and the average user does not need to change this. After you find this section, update the values accordingly. In our example, the new changes will look like this:

After you've made the above changes, click the "Save Changes" button in the upper right.

With one more step to go, we're almost done with the WordPress Site Migration! Continue to the next article to learn how to test your work.
