January 23, 2024
Navigate complex database migrations between MySQL, PostgreSQL, SQLite, and NoSQL systems while preserving data integrity.
Database migration is a critical process that requires careful planning, data mapping, and validation to ensure zero data loss and minimal downtime.
Migration Planning
Successful migrations start with thorough planning:
- Schema analysis: Map source to target structures
- Data type mapping: Handle incompatible types
- Constraint migration: Preserve relationships and rules
- Performance considerations: Optimize for target system
- Rollback strategy: Plan for potential issues
Common Migration Scenarios
- MySQL to PostgreSQL: Handle auto-increment and data types
- Oracle to MySQL: Convert PL/SQL to stored procedures
- SQL Server to PostgreSQL: Map proprietary functions
- Relational to NoSQL: Denormalize and restructure data
Data Validation and Testing
Ensure migration accuracy:
- Row count verification: Confirm all data transferred
- Checksum validation: Verify data integrity
- Performance testing: Benchmark query performance
- Application testing: Validate business logic
