Job description
Lead the end-to-end data migration to the COBAST core banking SaaS solution, ensuring data completeness, consistency, and usability. Define migration strategy, plans, and oversee data quality, reconciliation, and cutover.
Project overview
Context
COBAST aims to replace the legacy banking system with a SaaS core banking solution. The mission covers data recovery, definition of mapping and transformation rules, quality controls, reconciliations, migration repetitions, and cutover preparation. The consultant must ensure mastery of the migration process without replacing the functional managers of each domain.
