What’s changing with Upgraded URLs
Upgraded URLs let you enter the landing page portion of your URL and your tracking information separately in AdWords. Now you have the option to update your tracking information at your account, campaign or ad group without having to re-set your ad stats.

The Bottom Line
The deadline for upgrading your URLs is July 1st. At that time all URLs will be upgraded to yourdomain.com only and if you haven't created a tracking template to redirect your URLs through a click tracker (Kenshoo or Marin for example) or appended URLs with utms you will lose the ability to track your Google AdWords traffic in third-party analytics. It will also break your redirects from a third-party click tracker.
