Google announced that Universal Analytics will become the default for all Google Analytics, like it or not.
Google said:
Our goal is to enable Universal Analytics for all Google Analytics properties. Soon all Google Analytics updates and new features will be built on top of the Universal Analytics infrastructure. To make sure all properties upgrade, Classic Analytics properties that don’t initiate a transfer will be auto-transferred to Universal Analytics in the coming months.
If you want to upgrade sooner, Google made it easier with a two-step process to upgrade your existing properties from classic Google Analytics to Universal Analytics.
Google has a step by step instructions on how to do that over here.
