With this new code, you do not need to upload HTML file nor a meta tag verification nor DNS record rather you can just click an option of Google Analytics set up and verify the ownership.
It’s unfortunate that I have not seen much encouraging implementation of this code from many webmasters across the globe (I saw few top websites still using old Google Analytics Tracking code).
Guys, its time to migrate to the new asynchronous code from the old tracking GA for easy and new reporting features. The migration from old tracking code to new code is easy. Read here migration guidelines Google released after it introduced to us the new code.
So, try and test!!
