Amazon ElastiCache for Redis OSS: Redis OSS 5 end of extended support

End of Extended Support and version end of life for Redis OSS 5 on Amazon ElastiCache: 31 Jan 2029. After that date, ElastiCache attempts to upgrade caches still running it to a newer engine version under standard support.

Support ends , 31 Jan 2029

What breaks

31 Jan 2029 is the end of Extended Support and the version end of life for Redis OSS 5. If the engine is not upgraded, after that date Amazon ElastiCache attempts to upgrade it to a newer engine version that is supported under standard support. If that upgrade fails, AWS reserves the right to delete the cache, and states that it preserves the data from that engine before doing so.

What to do

  1. Upgrade the engine to a newer engine version before the end of Extended Support date. AWS lists this as the customer's responsibility.
  2. 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.
  3. Test the new version with your application before deploying it in production.
  4. AWS states that some existing ElastiCache for Redis OSS engines can also be upgraded to a Valkey engine.
