Google Analytics conversion goals now available on AdWords

In a post published on 29 April 2013, Google announced that

Starting in mid June, you’ll be able to import your Google Analytics goals into AdWords shortly after they’re configured. As usual, data for those goals will be available about two days later.

Google suggests that it’s better to track Goals through Analytics rather than AdWords for the following reasons:

Google Analytics Conversion Goals	AdWords Conversion Tracking
More complex, but provides more information about where your clicks are coming from. Ideal if you’re interested in the entire flow of customers through your site, not just conversions. Can include conversions from non-AdWords sources, so it’s a great comparison tool.	Less complex, but provides less information about where your clicks are coming from. Ideal if you’re interested only in conversions. Tracks conversions only from AdWords sources.

GA Goals will still be uniquely manageable from GA Admin. There can be discrepancies between the two, as Google explains here together with everything needed to let GA goals appear under your AdWords campaigns conversions list.

You can use both, they will not interfere each other so no need to change configuration.
