Redis Migration Services
Nextbrick provides end-to-end redis migration services for organizations moving between Redis versions, Redis deployment models, or cloud platforms. Our zero-downtime migration methodology has been validated across production Redis environments running mission-critical workloads.
Redis Migration Types We Handle
- Redis Version Upgrades — Redis 5 → 6 → 7 → current with compatibility validation and rollback planning
- Self-Managed to AWS ElastiCache — Migration from on-premise or VM-based Redis to ElastiCache for Redis
- Self-Managed to Google Cloud Memorystore — Migration to GCP-managed Redis with cluster mode support
- Self-Managed to Azure Cache for Redis — Migration to Azure-managed Redis tiers
- Redis OSS to Redis Enterprise — Migration from community Redis to Redis Enterprise with Active-Active and module support
- Single-Instance to Redis Cluster — Horizontal scaling migration with slot redistribution
- Redis Standalone to Redis Sentinel — High availability migration for non-clustered environments
- Cross-Region Redis Replication — Geographic distribution setup for DR and global serving
Zero-Downtime Redis Migration Methodology
Phase 1: Migration Planning
We analyze your current Redis deployment: data size, key count, TTL distribution, command patterns, client library versions, and application coupling. We identify version compatibility breaks, client library changes required, and operational risks before any migration work begins.
Phase 2: Target Environment Setup
We provision and configure the target Redis environment with the correct topology, persistence, replication, security, and monitoring settings before any data movement occurs.
Phase 3: Data Synchronization
We establish replication from source to target using Redis replication, RDB snapshot import, or live DUMP/RESTORE depending on the migration type. For cross-platform migrations, we use validated tooling to stream keyspace data with TTL preservation.
Phase 4: Application Validation
We run application integration tests against the target environment with production-representative data before cutover. This catches client library compatibility issues, command behavior differences, and keyspace assumptions that surface only under real application workloads.
Phase 5: Zero-Downtime Cutover
We execute cutover using read-replica promotion, DNS switchover, or client-side configuration change depending on your deployment model. Cutover windows are measured in seconds for well-prepared migrations. We maintain rollback capability throughout the cutover window.
Phase 6: Post-Migration Validation
We validate hit rates, latency, replication lag, and error rates in the new environment for 24–48 hours post-cutover and remain on standby for immediate incident response.
Redis Version Upgrade Compatibility Matrix
| From | To | Key Considerations |
|---|---|---|
| Redis 5.x | Redis 6.x | ACL system introduction, RESP3 protocol, new stream commands |
| Redis 6.x | Redis 7.x | Function API, multi-part AOF, OBJECT FREQ command, sharded pub/sub |
| Redis 7.0 | Redis 7.2+ | LMPOP/ZMPOP additions, sintercard, OBJECT HELP updates |
Redis Migration FAQ
How long does a Redis migration take?
Most Redis migrations complete within 1–3 weeks: 2–4 days for planning, 2–5 days for target setup and sync, 1 day for application validation, and minutes for the actual cutover. Large data volumes or complex application integrations extend timelines.
Can Redis be migrated with zero downtime?
Yes. With proper replication setup and cutover planning, Redis migrations can achieve zero application downtime. Nextbrick’s methodology targets sub-30-second cutover windows for well-prepared migrations.
What happens if the migration fails?
Nextbrick maintains rollback capability throughout the migration process. The source environment remains live and writable until post-cutover validation is complete, enabling immediate rollback without data loss.
