| Benefit | What it means for you | |---|---| | | Incremental replication + live switchover eliminates service interruption. | | Schema‑agnostic | Works with any JSON document shape; optional validation rules can be enforced during migration. | | Built‑in data‑quality checks | Checksums, conflict‑resolution policies, and customizable transformation pipelines guarantee fidelity. | | Cost‑aware planning | Predictive resource‑usage models let you size target clusters and estimate cloud spend before the move. | | Extensible plug‑in model | Supports custom adapters (e.g., SAP Hana, Elasticsearch) and scripting via JavaScript/Python. |

| Phase | Action | Detail | Success Criteria | |---|---|---|---| | | Run couchtuner assess | Scans source cluster, collects document count, size, indexes, replication factor, and network latency. | Assessment report with recommended target sizing and risk rating (Low/Medium/High). | | 1 – Planning | Create a migration plan (YAML) | Define source/target endpoints, transformation scripts, conflict‑resolution policy, and cut‑over window. | Plan validated ( couchtuner validate ). | | 2 – Pre‑Migration Validation | Dry‑run with 0% traffic | Executes adapters on a 0.1 % sample, writes to a staging target, runs full verification suite. | < 0.1 % error rate, no schema violations. | | 3 – Incremental Replication | Start continuous change capture | Data flows in near‑real time; existing reads continue against source. | Target lag ≤ 5 seconds (configurable). | | 4 – Cut‑over Preparation | Freeze writes (optional) | Application tier enters “read‑only” mode for the final sync window. | No new writes for ≥ 30 seconds. | | 5 – Final Sync & Verification | Drain remaining changes, run verification | Engine flushes the change queue, performs checksum comparison. | 100 % checksum match, document count parity. | | 6 – Switchover | Update DNS / load balancer | Traffic is redirected to the target endpoint. | Health checks pass for 5 minutes. | | 7 – Decommission | Retire source cluster | Optionally keep read‑only replica for 30 days as backup. | All backups archived, SLA compliance confirmed. | | 8 – Post‑Migration Review | Generate final report | Includes performance baseline, cost projection, and lessons learned. | Stakeholder sign‑off. | A: Migration CouchTuner supports a wide range of
