title: C2DM TO Google Cloud Messaging (GCM)
body: <p>As you may have seen, Google is migrating its Push Notification System.</p>

  <p>I guess I am not alone wondering : are the tokens obtained from C2DM still valid for GCM ?</p>
  
  <p>If not, it means that I need all my users to update my app with a new version updating the tokens on my servers ... </p>
  
  <p>OR </p>
  
  <p>I can keep the parallel systems which is something I don't think it's a good solution</p>
  
  <p>OR</p>
  
  <p>Continue using C2DM until it's finished, then I die with it :-)</p>
