Migration Couchtuner

Migration CouchTuner (hereafter ) is a purpose‑built automation framework that orchestrates the end‑to‑end migration of document‑oriented databases—primarily Apache CouchDB and Couchbase Server—from on‑premises, legacy clouds, or hybrid environments to modern, scalable targets such as Couchbase Cloud, Azure Cosmos DB (Cassandra API), AWS DocumentDB, or self‑managed Kubernetes clusters.

| 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. | migration couchtuner
