What Is Database Migration?
Database migration is the process of moving data, schema, and database objects from one database platform to another—for example, from Oracle to PostgreSQL, or from SQL Server to MySQL. It involves converting the schema, migrating all data with full integrity validation, converting stored procedures and triggers, testing application compatibility, and performing a production cutover.
Modern database migrations use logical replication and change data capture (CDC) to keep the target database in sync with the source during migration, enabling a near-instant cutover with minimal or zero downtime.
DharmOps has completed 500+ database migrations over 19+ years. We specialize in high-risk, high-complexity migrations—large enterprise databases, mission-critical systems, and tight downtime windows.
Key Migration Benefits
What you gain from a well-executed database migration.
50%+ Cost Reduction
Eliminate expensive Oracle and SQL Server licensing fees by moving to open-source or cloud-native platforms.
Zero-Downtime Migration
Continuous operation throughout the migration. Final cutover typically under 5 minutes using logical replication.
100% Data Integrity
Multi-stage validation including row counts, checksums, and referential integrity checks at every step.
Migration Paths We Support
Experienced with all major source-to-target database platform combinations.
Common Reasons to Migrate Databases
- Reduce licensing costs by moving to open-source databases
- Improve performance with modern database engines and features
- Modernize infrastructure for cloud-native deployment
- Consolidate multiple databases to reduce operational complexity
- Escape vendor lock-in and proprietary SQL extensions
- Scale more efficiently with PostgreSQL partitioning and replication
- Gain advanced features: JSONB, GIS (PostGIS), full-text search
- Meet compliance requirements with specific certified platforms
- Access to a larger talent pool (PostgreSQL/MySQL DBAs are more available)
- Reduce cloud costs by right-sizing to managed cloud databases
Is Your Migration Overdue?
Every year on a legacy proprietary database is another year of avoidable licensing costs and vendor lock-in. The longer you wait, the more data accumulates and the harder—and riskier—the migration becomes.
