You can either use the automatic plugin installer or your FTP program to upload it to your wp-content/plugins directory
the top-level folder. Don't just upload all the php files and put them in /wp-content/plugins/.
Activate the plugin through the 'Plugins' menu in WordPress.
Visit the Complete Update URLs panel.
Enter your new site location after backing up your WordPress database and click 'Update URLs'.
Copy your WordPress database to its new location.
That's it! Easy as pie!
