The permanent migration of Facebook users to its new site started this week, and will continue over the next few weeks, said a company spokesman, Media Post reported.

Since the new version of the site unveiled in July, Facebook has continuously made changes to it based on member feedback. Some users were against the upgrade formed a group called "Petition against the New Facebook", which has grown to nearly one million users, as of Thursday.

Facebook Product Manager Mark Slee wrote in a post on the company blog Wednesday that “30 million people are now using the new site,” Media Post reported.

"Based on your feedback, we've simplified the top navigation. We also heard that people were confused about how to find their applications, so we are moving the Applications menu to the menu bar at the bottom of every page. This will make it much easier to get to your favorite applications whenever you want,” Slee added.
