If we plan to upgrade Drupal version to any version later to 7.34 from 7.28, do we need to perform any checks or steps before and after upgrade?

  • None of the Apigee components will be affected and there is no need to perform any check before or after the upgrade.
  • Also make sure the DB and the code is backed up before starting the upgrade.
  • If the portal is accessible only to internal network then the security vulnerabilities will not have much impact as only internal users will be accessing the portal. If the case is otherwise it is strongly recommended to do an upgrade on the portal.
  • By default, Drupal is installed in /var/www/html. You need to backup this folder before proceeding with the upgrade.
#Check status of the drupal instance: 
drush status 

# Take backup using Drush Archive 
drush archive-dump --destination=../backups/dc-20150903.tar 
  • In case of drush archive-dump failing, it might be because MySQL server is not reachable. To get MySQL server information, you can look at the databases array in /var/www/html/sites/default/settings.php.
  • The below link has more details.
