Below is an original video I created and uploaded to YouTube.
It shows how to upgrade from WordPress 2.7 to 3.x in just a few minutes. In the past, I used to FTP the entire set of hundreds of files to the server, which alone could take 10-20 minutes. Now, I just upload one file and extract it on the server, using CPanel’s “FileManager”
Now beginning with the 3.x versions of WordPress, this is no longer needed, because you can easily upgrade from within the dashboard, a really fast and amazing feature, and one of the reasons I love WordPress.
