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.

Requirements

What you need to get started

Source Database Access

required

Read access to source database with permissions to export schema and data.

Target Environment

required

Provisioned target database instance with appropriate sizing and configuration.

Application Inventory

required

List of applications and services that connect to the database.

Downtime Window

recommended

Defined maintenance window for cutover if zero-downtime is not possible.

Performance Baselines

optional

Current performance metrics for comparison after migration.

Common Challenges We Solve

Problems we help you avoid

Schema Incompatibility

Impact: Data types and constraints differ between database platforms.
Our Solution: Custom schema conversion with thorough testing of all data types and edge cases.

Stored Procedure Migration

Impact: Business logic in stored procedures may use platform-specific features.
Our Solution: Manual review and conversion of stored procedures with functional testing.

Performance Degradation

Impact: Queries optimized for one platform may perform poorly on another.
Our Solution: Query analysis, index optimization, and execution plan tuning.

Frequently Asked Questions

How long does a database migration typically take?

Database migration timelines range from 4-12 weeks depending on database size, complexity, and the platforms involved. Simple migrations between similar platforms may take 4-6 weeks, while complex heterogeneous migrations can take 10-12 weeks.

Can you migrate stored procedures and triggers?

Yes, we migrate all database objects including stored procedures, triggers, functions, and views. For heterogeneous migrations, these require manual conversion and thorough testing to ensure business logic is preserved.

How do you ensure zero downtime during migration?

We use continuous data replication (CDC) to keep source and target databases synchronized. During cutover, we perform a brief pause on writes, ensure final synchronization, redirect applications to the new database, and resume operations-typically within minutes.

What if the migration fails?

We maintain the source database in full operation until validation is complete. Rollback procedures are tested before cutover, allowing instant reversion to the source database if any issues arise during go-live.

Do you handle large databases?

Yes, we have migrated databases exceeding 50TB. For large databases, we use parallel data loading, network optimization, and incremental approaches to minimize migration time while maintaining data integrity.

What databases do you support?

We support all major database platforms including MySQL, PostgreSQL, Oracle, SQL Server, MongoDB, Amazon RDS, Aurora, Azure SQL, Google Cloud SQL, and more. We handle both relational and NoSQL databases.
