Facebook is migrating to one pixel that combines both the Conversion Tracking pixel and the Custom Audience pixel.
This new and improved Facebook pixel will track activity on mobile, tablet, and desktop ads, and can be used by advertisers to serve dynamic ad formats. This marks a great improvement from Facebook Exchange's retargeting, which could only track desktop activity and serve display link ads based on cookie retargeting.
If you’ve never created a Facebook pixel, there is no need to worry about converting over to the new one. However, if you have existing pixels, you’ll want to implement the change as soon as possible. The change does require effort to integrate, especially if you have existing retargeting campaigns set up. The new pixel code will need to be installed on your site pages to effectively track conversions and retarget before all legacy Facebook pixels are disabled.
Here are all the important dates you need to know.

Resources To Help Migrate Over to the New Pixel
In order to help monitor the migration of the old pixels to one new pixel, Facebook has implemented tools to assist:
Pixel Migration Dashboard
Available in Facebook's Ads Manager, this will ensure that you have installed the base code and any necessary events in the same place as the old pixel.
Available in the Google Chrome App store, Pixel Helper is to ensure your pixels are installed correctly. If you are viewing this in Chrome, you can download the app here: https://chrome.google.com/webstore/detail/facebook-pixel-helper/fdgfkebogiimcoedlicjlajpkdmockpc
