title: Upgrading Django, how to get manage.py
body: <p>I am looking to upgrade from Django 1.5 to 1.6. </p>
  
  <p>So I have set up a virtualenv, downloaded everything that was in my pip freeze (but changed the Django version).</p>
  
  <p>I tried </p>
  
  <pre><code>python manage.py runserver 
  </code></pre>
  
  <p>but I am getting an error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "manage.py", line 2, in &lt;module&gt;
      from django.core.management import execute_manager
  ImportError: cannot import name execute_manager
  </code></pre>
  
  <p>A google tells me this is because execute_manager has gone in Django 1.6. But my manage.py file is from a few versions back (1.3 probably). </p>
  
  <p>Is there a preferred way to upgrade the manage.py?</p>
  
  <p>That gets put there when you run startproject. Should I just look in  the Django package for an up to date manage.py? Or is there a preferred way to upgrade? Is there anything else that needs copied / changed at the same time?</p>
