title: TFS 2015 upgrade stuck
body: <p>We are upgrading to TFS 2015 and it seem like almost 8 day the system is still trying to upgrade.  It is stuck on job step<img src="https://i.stack.imgur.com/3iHZ6.jpg" alt="enter image description here"></p>
  
  <p>I'm not sure if I should reboot because one of the article <a href="http://nokitel.im/index.php/2015/03/24/tfs-2013-upgrade-project-collection-stuck-offline-servicing-state/" rel="nofollow noreferrer">http://nokitel.im/index.php/2015/03/24/tfs-2013-upgrade-project-collection-stuck-offline-servicing-state/</a> said rebooting would make the process start all over.  Any suggestions?
