Database Migration Services
Zero-Downtime Database Transitions
Migrate your databases between platforms with complete data integrity, minimal downtime, and comprehensive validation. From MySQL to PostgreSQL, on-premise to cloud, or legacy to modern systems.
What is Database Migration?
Seamless transitions between database platforms
Database migration involves moving your data from one database management system to another while preserving data integrity, relationships, and business logic. This includes schema conversion, data transformation, stored procedure migration, and performance tuning.
Our database migration services cover all major platforms including MySQL, PostgreSQL, Oracle, SQL Server, MongoDB, and cloud-native databases like Amazon RDS, Azure SQL, and Google Cloud SQL. We handle both homogeneous migrations (same database type) and heterogeneous migrations (different database types).
Every migration includes comprehensive validation, rollback procedures, and performance testing to ensure your applications work seamlessly with the new database platform.
Why Choose DevSimplex for Database Migration?
Proven expertise across all database platforms
Database migrations are high-stakes projects where errors can mean data loss or extended downtime. Our team has successfully migrated over 200 databases across industries including finance, healthcare, and e-commerce.
We use advanced replication and synchronization techniques to achieve true zero-downtime migrations. Your applications continue running on the source database while we validate the target, then perform a rapid cutover that typically takes minutes, not hours.
Our validation framework catches discrepancies at every stage-from initial data transfer to final reconciliation. We verify record counts, checksums, and business-critical data integrity before any cutover.
