In an Edge for Private Cloud installation of Apigee Developer Services portal (or simply, the 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.
Upgrade Drupal core
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 7.59).
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 Upgrade the portal.
If during a Private Cloud upgrade (for example, from 4.18.05 to 4.19.01), the Apigee update utility actually downgrades your version of Drupal, you might need to re-run the Drupal upgrade utility. For more information, see Re-run the Drupal upgrade.
- You must execute the Drush
(Drupal Shell) commands from the root directory of the portal site. By default, the
portal is installed at:
Determine your current Drupal version
Before you start the Drupal update, you can determine your current Drupal version by running
the following command from the Drupal installation folder. By default, Drupal is installed in
drush status | grep 'Drupal version'
You should see output in the form:
Drupal version : 7.54
If you installed Drupal in a directory other than
make sure to change to that directory before running the
Update the Drupal version
This section describes how to use Drush commands from a command line to update your Drupal version. See also Updating Drupal Using Drush (Drupal.org).
To update your Drupal installation:
- Change to the
/opt/apigee/apigee-drupal/wwwrootdirectory, or the directory where you installed the portal.
- Make a full backup of all files, directories, and databases. Save the backup in a location
outside of the Drupal installation. For complete instructions, see
Back up the portal.
If you made modifications to files such as
sitesdirectory), you will have to reapply the changes after the update. You will also need to reapply any customizations made in the
- Put your site into maintenance mode:
drush vset --exact maintenance_mode 1
drush cache-clear all
- Install the desired version of Drupal by using the following command:

- Take your site out of maintenance mode:
drush vset --exact maintenance_mode 0
drush cache-clear all
Upgrade PHP and Drupal contrib modules
When you upgrade Drupal using the above instructions in this section, modules used by Drupal such as contrib and PHP are also upgraded. However, you should keep up with the latest Drupal modules in between Private Cloud releases.
Note that if the module is in
/profiles/apigee/modules/contrib, you can replace
it with a newer version of that module by storing the newer version in
/sites/all/modules/contrib. Edge for Private Cloud uses the newer version in
/sites/all/modules/contrib rather than the older version in
/profiles/apigee/modules/contrib. For more information, see
If you install a new Private Cloud version that includes a more recent version of the module
previously stored in
/sites/all/modules/contrib, remove the module from
/sites/all/modules/contrib. For more information, see
modules and themes (Drupal.org).
What if I encounter an issue during the update?
Restore your site to its previous state using the backup files that you created. Contact Apigee Edge Support and provide any error messages that were reported during the update.
