  "impact": "After 31 Jan 2027, caches that still run Redis OSS 6 move to ElastiCache Extended Support automatically, at an additional cost. Extended Support provides:\n\n- Security updates for critical and high CVEs for the cache and cache engine\n- Bug fixes and patches for critical issues\n- Support cases and troubleshooting help within the standard ElastiCache service level agreement\n\nAWS states that customers are notified before Extended Support pricing starts. Extended Support lasts up to 3 years and covers only the latest supported patch version of each major Redis OSS version. After it ends, ElastiCache attempts to upgrade the engine to a newer version under standard support.",
  "migration_path": "1. Upgrade to a supported version. AWS states that you can opt out of Extended Support at any time this way. The end of standard support and end of Extended Support dates are in the [ElastiCache versions for Redis OSS end of life schedule](https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/engine-versions.html#deprecated-engine-versions).\n2. On a node-based cluster, start the upgrade by modifying the cluster or replication group and specifying a new engine version. See [Modifying a replication group](https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/Replication.Modify.html).\n3. Test the new version with your application before deploying it in production.\n4. AWS states that some existing ElastiCache for Redis OSS engines can also be upgraded to a Valkey engine.",
