Data Migration Tool

The tool enables automated planning and execution of migrations between databases. It discovers source schemas, applies mapping rules to target schemas, transfers data in controlled batches, and performs post-migration validation. By separating planning, extraction, transformation, and loading phases, it supports repeatable migrations with auditable records. The approach emphasizes data integrity through row-count verification and checksum-style checks, while providing rollback options if the target supports transactional operations. The core differentiators are strong schema mapping capabilities, batch-oriented transfer with retry logic, and an end-to-end audit trail suitable for compliance. Typical use cases include upgrading a GBase deployment, consolidating legacy shards, and migrating to a modern target database with minimal disruption. The tool is designed for data engineers and DBAs who manage large-scale migrations and require reproducible results, traceability, and performance controls. Core features include schema discovery, mapping configuration, batched data transfer, transactional loading, and extensive validation. Advanced users can enable incremental migrations, parallel processing, and custom transformation rules for complex data types. The absence of UI focus in this specification highlights its emphasis on domain logic, reproducibility, and governance in enterprise environments.
