HexaRocket now supports SQL Server to Yugabyte Database Migrations (November, 2025)

We’re excited to announce a significant expansion of HexaRocket’s cross-platform modernization capabilities. SQL Server to YugabyteDB database migration support including Schema migration, Data migration and CDC is now officially available.

This enables enterprises to move from traditional SQL Server deployments to YugabyteDB’s distributed PostgreSQL architecture with automated schema conversion, high-speed parallel data movement, and optional CDC-based continuous synchronization.

As YugabyteDB is fully PostgreSQL-compatible, HexaRocket required no engine-level modifications, making the SQL Server → YugabyteDB migration experience seamless, stable, and extremely efficient.

This release positions HexaRocket among the world’s very few platforms that can migrate SQL Server workloads into a distributed SQL ecosystem, without complex rewrites, risky ETL processes, or long downtime windows.

Why SQL Server → YugabyteDB Migration Matters

As organizations modernize applications for distributed, cloud-native, and multi-region environments, YugabyteDB is increasingly preferred for:

• Horizontal scaling with PostgreSQL compatibility
• Ultra-low-latency multi-region deployments
• Strong fault tolerance & high availability
• Cloud-agnostic and Kubernetes-native operations
• Freedom from licensing constraints

However, SQL Server → Yugabyte migrations are traditionally challenging due to -

• T-SQL rewrite complexity
• SQL Server-specific datatypes and collations
• Identity/sequence model differences
• Case sensitivity and naming constraints
• Manual ETL pipelines for large datasets
• No unified schema + data + CDC migration platform
• Difficulty running SQL Server and Yugabyte in sync during phased cutovers

HexaRocket eliminates these challenges through a fully automated, validated, and restart-safe migration pipeline.

1. SQL Server → Yugabyte Schema Migration

HexaRocket now provides complete schema transformation from SQL Server to YugabyteDB.

Capabilities include -

• Automatic conversion of SQL Server objects to PostgreSQL-compatible structures
• Intelligent mapping of datatypes, identities, defaults, constraints & indexes
• T-SQL → PL/pgSQL conversion guidance
• Handling of case sensitivity, schema naming, and collation differences
• Schema validation with recommendations for distributed SQL best practices
• YugabyteDB receives a clean, optimized, and ready-to-deploy schema with minimal manual intervention.

2. High-Speed Parallel Data Migration

HexaRocket’s distributed data engine now supports SQL Server → Yugabyte bulk loading with -

• High-throughput parallel workers
• Fault-tolerant loaders optimized for distributed SQL
• Automatic resume/restart for long-running jobs
• Efficient handling of multi-terabyte datasets
• Row-by-row and batch validation during ingestion

Designed to fully utilize Yugabyte’s sharded architecture for maximum performance.

3. Real-Time CDC (Zero-Downtime Cutover)

HexaRocket now enables continuous synchronization during migration windows -

• SQL Server transactional log-based CDC ingestion
• Consistent, order-preserving change streaming
• Low-latency apply of changes from SQL Server into YugabyteDB clusters
• Retry handling & conflict detection
• Ensures both systems remain in sync until final cutover

Ideal for phased or zero-downtime modernization.

4. Unified UI for End-to-End Migration Control

The SQL Server → Yugabyte migration experience offers the same powerful UI as other connectors:

• Start, Pause, Resume pipelines
• Table-level operations & selective migration
• Real-time progress, throughput, and lag dashboards
• Automatic reprocessing of transient failures
• Worker scaling and resource tuning
• Alerts, health checks & performance insights

Everything is accessible through HexaRocket’s intuitive control plane.

Designed For

This release is built for:

• Enterprises modernizing SQL Server workloads into distributed SQL
• Organizations moving away from licensing constraints toward cloud-native DBs
• Teams adopting PostgreSQL-compatible architectures for microservices
• Companies deploying multi-region, multi-cloud, or Kubernetes-first solutions
• Businesses requiring strict uptime, rollback safety, and compliance-ready pipelines

Whether it’s modernizing monoliths or enabling cloud re-platforming, HexaRocket delivers a safe, automated pathway from SQL Server to YugabyteDB.

Strengthening HexaRocket’s Universal Migration Vision

With this release, HexaRocket expands its support matrix for distributed SQL modernization.

Supported as of November 2025:

• Oracle → PostgreSQL (Schema, Data, CDC)
• PostgreSQL → Oracle (Schema, Data, CDC)
• Oracle → Oracle (Data + CDC)
• SQL Server → PostgreSQL (Schema, Data, CDC)
• Oracle → BigQuery (Schema, Data, Batch CDC)
• Oracle → YugabyteDB (Schema, Data, CDC)
• SQL Server → YugabyteDB (Schema, Data, CDC)
• Additional distributed SQL connectors under development

HexaRocket continues to unify schema migration, bulk data migration, and real-time CDC for all major databases.
