Data Migration

Planned transfer of supported data between systems, databases or formats with mapping, validation and migration checks appropriate to the project.

From $100 · 1-4 weeks

Overview

Migration work covers analyzing source and target structures, writing field-level mappings and transformation scripts, and running trial migrations on a copy before the final transfer. We check record counts, referential integrity and sample values after each run, and agree a cutover plan that includes a rollback option. You receive the migration scripts, a validation report comparing source and target, and a list of records that needed manual handling.
