title: Neo4j restore asks for DB upgrade
body: <p>I have an instance in AWS hosting a Neo4j DB.
  The version im using is 2.3.1.
  I backed it up using "neo4j-backup".
  I then zipped the files and uploaded to an external storage.
  I wanted to restore the DB to another instance I have using the same version (2.3.1), so I copied the files to the same folder the 1st instance is using.</p>
  
  <p>When I run the neo4j console command it states:</p>
  
  <blockquote>
    <p>ERROR Neo4j cannot be started, because the database files require upgrading and upgrades are disabled in configuration. Please set 'allow_store_upgrade' to 'true' in your configuration file and try again.</p>
  </blockquote>
  
  <p>Of course the "allow_store_upgrade" is commented out,
  Do I have to do the upgrade when restoring?
  How can I find the DB version?</p>
