Amazon announces Extended Support for ElastiCache version 4 and version 5 for Redis OSS

Amazon ElastiCache now offers Extended Support for ElastiCache versions 4 and 5 for Redis OSS, allowing customers to maintain critical workloads on these versions for up to three years beyond the standard support end date. This new offering addresses the needs of customers who require additional time to plan and execute version upgrades due to application dependencies or large-scale deployment complexities.

Standard support for ElastiCache versions 4 and 5 for Redis OSS will end on January 31, 2026. After this date, clusters not upgraded to a supported version will be automatically enrolled in Extended Support. During the Extended Support period, Amazon ElastiCache will continue to provide critical security updates for Common Vulnerabilities and Exposures (CVEs) and critical defect fixes for these Redis OSS versions. Customers can upgrade using service update APIs or Modify APIs for their cache clusters and replication groups. We recommend upgrading to the latest ElastiCache for Valkey version, where customers can benefit from 20% lower price, improved performance. To get started and learn more about the benefits, see our blog.

Amazon ElastiCache Extended Support is available in all AWS Regions, including the AWS GovCloud (US) Regions and China Regions. The start date for Extended Support charges will not be earlier than February 1, 2026. Learn more about Extended Support, including supported engine versions, in the Amazon ElastiCache user guide.
