Data mapping, transformation, and normalization as needed

Scripted or tool-based migration for high-volume and complex datasets

Support for migrating stored procedures, views, and triggers (where supported)

3. Post-Migration Validation

Rigorous data validation and integrity checks

Performance benchmarking and tuning in the target environment

Compatibility testing with connected applications and front-ends

Rollback and backup strategies for risk management

4. Optimization and Support
