title: Recover Arangodb databases from /var/lib/databases directory?
body: <p>In some beta version of Arangodb 3.4 my database crashed while I tried to add a view via arangosh. Because I were not able to start the database anymore, it was not possible to make a backup (database dump).</p>
  
  <p>I just wanted to install the newest Arangodb 3.4.2.1 then, but that failed because my CPU was to old (no SSE 4.2 support). So I bought a new computer, sat up a new linux, copied the databases to /var/lib/arangodb3/databases, started a new installation of Arangodb in which it even asked me, if the current databases should be upraded. I confirmed that.</p>
  
  <p>Unfortunately it hasn't found the databases in that directory, so I have now just acces to the system database.</p>
  
  <p>My question is: Can I recover the databases which are laying in /var/lib/arangodb3/databases somehow?</p>
