The problem we set out to solve
Migrating Redis in production has always been a high-stakes operation. Traditional approaches like snapshot-based tools, DIY replication scripts, and maintenance-window cutovers all require some combination of downtime, application changes, and custom plumbing that gets thrown away afterward.
We built Eden to eliminate that trade-off entirely. Eden deploys as a proxy layer between your application and your databases, enabling live migrations with zero downtime and zero code changes.
Independent validation by Redis
The Redis team independently evaluated Eden's migration capabilities, running a series of tests that pushed Eden under real production conditions. Their goal was straightforward: find where it breaks.
Their conclusion? It didn't. The Redis team published a detailed technical report documenting their findings from both a local baseline test and a live cloud migration from AWS ElastiCache to Redis Cloud.

What they tested
The Redis team designed their evaluation around real-world conditions, not a whitepaper demo. They ran two tests:
- Local baseline: Two Redis 7.x instances with ~144k keys under ~33k ops/sec of sustained read/write traffic
- Live cloud migration: AWS ElastiCache to Redis Cloud with TLS enabled, ~70k keys, ~40k req/sec, and continuous TTL churn
Both tests used Eden's big-bang migration strategy with automatic cutover, meaning Eden handled the entire lifecycle without manual intervention.
Results
Local baseline
| Metric | Value |
|---|---|
| Keys migrated | ~144k |
| Duration | ~2 minutes |
| Throughput | ~33k ops/sec sustained |
| Downtime | None |
| App changes | None |
AWS ElastiCache → Redis Cloud
| Metric | Value |
|---|---|
| Keys migrated | ~70k |
| Duration | ~7 minutes |
| Throughput | ~40k req/sec sustained |
| TLS | Enabled |
| Downtime | None |
| App changes | None |
In both tests, the application maintained full connectivity throughout. No reconnects, no errors, no write freezes. The cutover happened automatically once the destination reached full coverage.
How Eden compares
| Aspect | Traditional tools | Eden |
|---|---|---|
| Downtime | Required | None |
| App changes | Usually required | None |
| Observability | Minimal | Full end-to-end |
| Cutover | Manual coordination | Automated |
| Throwaway code | Significant | None |
| Rollback | Restore from backup | Instant |
When to use Eden for migrations
Eden is purpose-built for teams where database migrations carry real production risk:
- High-throughput workloads that can't tolerate write freezes
- Large datasets where replication takes hours, not minutes
- Compliance or SLA requirements that rule out maintenance windows
- Teams that need instant rollback without restoring from backups
- Organizations consolidating across cloud providers or managed services
As the Redis team noted in their evaluation, Eden shifts migrations from a high-risk event you brace for into a controlled, observable process.
