title: Git how to rebuild lost central repository from cloned copies
body: <p>We had a central Git repository on a separate server. All the team members have cloned it to their local machines and did pull/push to that central repository. </p>
  
  <p>Unfortunately, the machine with the central repo has crashed and is not recoverable. </p>
  
  <p>Now, how can we rebuild a central repo again using the cloned copies from developers' machines and how to sync the local changes from different cloned repos to this rebuilt central repo?</p>
  
  <p>Thanks for your help. </p>
