How can I convert an existing project to angular-cli?
<p>I just tried <a href="https://github.com/akveo/ng2-admin" rel="nofollow noreferrer"><code>ng2-admin</code></a> and it's looking great; all of the features are really good. How can I convert this project to <code>angular-cli</code>?</p>

<p>I tried with <code>ng init</code>, but it is overwriting the existing code in the <code>app</code> folder. How can I convert this project to <code>angular-cli</code> without any impact?</p>
