ElastiCache Valkey Migration

Amazon ElastiCache for Redis clusters running compatible versions can be migrated to Valkey, a community-driven, open-source in-memory data store. Valkey on ElastiCache can reduce licensing costs while maintaining API compatibility.

Implementation Effort: Medium - Estimated time: 1-4 hours. Test application compatibility with Valkey, then perform an in-place engine migration.

What We Detect

• Valkey migration candidates -- ElastiCache Redis clusters running engine versions compatible with Valkey migration, where switching engines can reduce costs

Why It Matters

AWS offers ElastiCache for Valkey at a lower price point than Redis. Since Valkey is API-compatible with Redis, most applications can migrate with minimal or no code changes while benefiting from lower node-hour pricing.

Recommendations

1. Verify your application uses standard Redis commands compatible with Valkey
2. Test in a non-production environment first
3. Perform the migration via the AWS Console or CLI
