Edge for Private Cloud v. 4.17.05
In an Edge for Private Cloud installation of the Developer Services portal, you might get a notification that a new version of Drupal is available. A new version can mean a Drupal feature release, patch, security update, or other type of Drupal update. In the case of a security update, you want to upgrade your installation of Drupal as soon as possible to ensure that your site remains secure.
The procedure below describes how to update a Private Cloud installation of Drupal 7.x.y to another minor version (for example Drupal 7.54 to 7.56).
Please note the following:
This procedure only updates your installation of Drupal. It does not update the Apigee software that ships as part of the portal. For information on upgrading the Apigee portal software, see Upgrading the Developer Services portal.
