[Announcement] Extension to Mandatory Upgrade Schedule for Amazon Aurora

Dear Amazon Aurora customers,

Last month, we informed you via email and the Personal Health Dashboard of a mandatory upgrade to Aurora v1.14 in your maintenance window in the period between September 18, 2017 at 00:00 UTC and September 24, 2017 at 23:59 UTC.

We missed including some of you or some of your clusters in that notification. Proceeding with the upgrade on the original timeline means some of you won’t have adequate time to test your production loads on Aurora v1.14.

As a result, we are resetting the timeline for the mandatory upgrade that was previously announced. No further action is required for clusters already running Aurora v1.14. For all other clusters running earlier versions of Aurora, you have the option to upgrade your DB clusters to the latest version of Aurora through October 22, 2017 at 23:59 UTC. See the following link for instructions on how to perform the upgrade: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Aurora.DatabaseEngineUpdates.html.

We encourage you to use this period to test your workload against the latest release. You can clone your existing DB clusters (http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Aurora.Managing.Clone.html), which will automatically receive the latest software. Once the clone has been created, you can subject it to workload tests to verify that there are no performance or stability issues.

If you haven’t upgraded your database clusters by the end of the above period, we will automatically upgrade your DB clusters to the latest version of Aurora in your maintenance window in the period between October 23, 2017 at 00:00 UTC and October 29, 2017 at 23:59 UTC. We recommend that you review the maintenance windows for eligible instances as they often default to the same timeframe.

Should you have any questions or concerns, the AWS Support Team is available on the community forums and through AWS Premium Support at http://aws.amazon.com/support.

Sincerely,
Amazon Web Services
