upgrade angular 1 to 2
<p>I have my angular app with <strong>version 1</strong> so can i <strong>upgrade</strong> it with angular version 2</p>

<p>We started to design a new project that designated to be built with Angular as each of our previous, the importance of this project is very high and it's going to live and maintained for at least years.</p>

<p>Angular 2.0 has came in  beta mode and it seems like everything is about to change, $scope is out, directives are out and the whole DI concept is about to change.</p>

<ol>
<li>Is there a migration path/strategy to be considered in the next few months?</li>
<li>If we built the project using 1.x, what action do we need to take during development to ensure a clean migration?
Are those 2 versions can be considered as 2 different framework? </li>
</ol>

<p>Please help me to sort out.</p>
