Cross-Platform Data Migration Without Compromise
Whether you are consolidating databases after a merger, moving from Oracle to PostgreSQL for cost savings, or lifting SQL Server to Azure SQL, data migration is high-stakes work where a single missed row can break compliance or customer trust. Our migration engineers design end-to-end transfer pipelines with validation at every stage.
We handle schema conversion, data type mapping, stored procedure translation, character encoding issues, and large-table strategies using parallel bulk copy, change data capture, and incremental sync — culminating in a zero-downtime cutover with automated reconciliation reports.
What We Build
-
Cross-Database Migration
SQL Server ↔ PostgreSQL ↔ MySQL ↔ Oracle with automated schema conversion, type mapping, and stored procedure rewrites.
-
Cloud DB Migration
On-premise to Azure SQL, AWS RDS, or Google Cloud SQL with network tunneling, bandwidth optimization, and cost planning.
-
Zero-Downtime Cutover
CDC-based replication, dual-write periods, DNS switching, and read-only freeze windows measured in minutes, not hours.
Key Data Migration Capabilities
End-to-end expertise tailored to your data and platform requirements.
Schema Conversion
Automated DDL translation with manual review for platform-specific features, sequences, triggers, and user-defined types.
Bulk Data Transfer
Parallel BCP, pg_dump/pg_restore, Oracle Data Pump, and custom ETL with compression and resume-on-failure support.
Change Data Capture
Real-time replication during migration window to keep source and target synchronized until final cutover moment.
Data Reconciliation
Row counts, checksums, sample comparisons, and business-rule validation reports proving 100% data fidelity.
Migration Testing
Staging environment rehearsals, performance benchmarks, application integration tests, and rollback drills before production.
Cutover Orchestration
Minute-by-minute runbooks, communication plans, monitoring dashboards, and war-room support during the live switch.
Our Data Migration Stack
Battle-tested tools and platforms for reliable data operations.
Our 4-Step Migration Process
A structured workflow that delivers predictable, high-quality outcomes.
Assessment & Planning
Inventory source systems, map schemas, estimate data volumes, select migration tools, and define cutover strategy with timelines.
Pilot Migration
Migrate a representative subset to staging, validate conversion accuracy, benchmark performance, and refine the execution plan.
Full Data Sync
Initial bulk load followed by incremental CDC sync, keeping target current while source remains the production system of record.
Cutover & Reconcile
Execute final sync, switch application connections, run reconciliation reports, and provide hypercare support for 30 days post-migration.
