How long does Acquia take to upgrade all environments on my application?

After the upgrades in non-production environments are complete, you have approximately 14 calendar days to test all upgraded environments and verify that the essential Cloud Platform and Drupal site features work as expected. This includes automations and scheduled cron jobs. For any technical issues discovered after the upgrades, you must create a Support ticket.

If no critical issues are identified after 7 days, Acquia sends a second maintenance notification for your production environments. Your production environments are upgraded at least 7 calendar days after that, depending on the maintenance window availability.

Therefore, you can expect production and non-production environments to run on two separate versions of Cloud Platform for approximately 2 weeks, unless otherwise noted.
