I received notification of a scheduled maintenance window for my ElastiCache node, but I need to postpone the scheduled maintenance. How can I do this?

AWS periodically schedules maintenance windows for ElastiCache nodes, typically to update or upgrade the underlying hardware. AWS notifies ElastiCache customers when maintenance windows are scheduled because the associated ElastiCache nodes are inaccessible during the maintenance window.

You can postpone scheduled maintenance for up to a week, but you cannot modify the maintenance window to occur before it is scheduled. You can also manually replace the node before the scheduled maintenance window.

Depending on the type of ElastiCache node that you are using (Redis or Memcached), you can pursue additional options. For more information about these options, see Actions You Can Take When a Node is Scheduled for Replacement.

Note: ElastiCache only sends scheduled maintenance window notifications to customers for planned upgrades or patches. If you need to adjust the preferred maintenance window for your cache clusters during the course of normal operations, follow the guidance at Modifying an ElastiCache Cluster or Modifying a Cluster with Replicas.
