  1. Go to the Downloads section on the DataCore Support Portal.

  2. Scroll down and open the Swarm toggle

    • Whenever a new component version is available (such as a new release of Content Gateway), these bundles are updated and the ZIP file name changes to reflect the release date for the bundle.

  3. From the Documentation Archive page, download the PDF specific to your bundle. 

    • The comprehensive PDF that matches all of the components at those versions is uploaded to the Documentation Archive using a filename that includes that same release date for its matching bundle.

    • The Swarm online documentation is continually updated to the current release; because the PDF is a snapshot that is tied to a bundle release, consider it the definitive source for that bundle.

    • Our Support team's searchable Knowledge Base contains both technical articles and the very latest documentation, which might be newer than your installed version. 

  4. Expand your software bundle. In the top-level directory of the bundle, locate and read the README.txt for the version guidance on using the bundle.

  5. Open the PDF you downloaded for your bundle and see the Release Notes for each component, which include upgrade instructions as well as changes and watch items.

    4. When the feed completes, make it primary.

    5. If you are on Gateway 5.4.1, upgrade to Gateway 7.0.

    6. Configure gateway.cfg indexerHosts to point to your new Elasticsearch 6 cluster and restart CloudGateway, using sudo systemctl restart cloudgateway command.
