title: Artifactory upgrade from 6.4.1 to 7.x version
body: <p>I'm trying to upgrade Jfrog artifactory from 6.4.1 version to the latest 7.x version.
  I'm not able to find the upgrade path in the <a href="https://www.jfrog.com/confluence/display/JFROG/Upgrading+Artifactory" rel="nofollow noreferrer">manual</a>.</p>
  <p>Is there an official document on the upgrade path for the same?</p>
