Azure SQL Database Data Sync Retirement: Migration Scenarios and Recommended Alternatives

Why azure sql data sync retirement matters Azure SQL Data Sync relies on: * Triggers * Metadata tables * Hub-and-spoke topology While functional, this architecture introduces complexity, performance overhead, and operational risks, especially as data volumes and workloads grow. Microsoft’s long-term direction favors scalable, resilient, and observable data integration services, such as Azure Data Factory (ADF) and event-driven replication patterns. If you are currently using Data Sync, planning a migration early is strongly recommended.

DIAGRAM 1: CURRENT STATE – Azure sql data sync (BEFORE RETIREMENT) This diagram represents the existing topology, where multiple databases are synchronized using Azure SQL Data Sync into a single consolidated database. Characteristics * Trigger‑based synchronization * Additional metadata tables * Limited observability * Service approaching retirement DIAGRAM 2: TARGET STATE – Azure data factory based consolidation This diagram shows the recommended replacement architecture using Azure Data Factory. Advantages * No triggers or sync metadata tables * Parallel ingestion * Built‑in retry, monitoring, and alerting * Fully supported and future‑proof DIAGRAM 3: Incremental replication logic (ADF) This diagram explains how minimal data loss is achieved using incremental replication..
