Data Migration Tester information

What is a data migration tester?

Data Migration Testers are professionals responsible for verifying that data is accurately and securely transferred between storage systems, databases, or applications during a migration project. Their main tasks include planning and executing test cases, validating data integrity, identifying discrepancies, and ensuring the data migration meets business and technical requirements. They often work closely with data analysts, developers, and project managers to ensure a smooth transition with minimal data loss or corruption.

What skills and qualifications are needed to be a data migration tester?

To thrive as a Data Migration Tester, you need strong analytical skills, a background in database management, and experience with data validation and testing methodologies. Familiarity with SQL, ETL tools, and data migration frameworks, along with knowledge of relevant testing tools like Selenium or Informatica, is typically required. Attention to detail, problem-solving abilities, and effective communication are crucial soft skills for ensuring data integrity and collaborating with project teams. These skills ensure accurate data transfer, minimize business disruption, and support the success of complex migration projects.

What are common challenges faced by data migration testers during large-scale migration projects?

Data Migration Testers often encounter challenges such as data inconsistencies between source and target systems, managing tight project timelines, and ensuring minimal downtime during the migration process. Coordinating with multiple teams—including developers, business analysts, and database administrators—is essential to resolve issues quickly and maintain data integrity. Testers must also develop robust test plans and use automation tools to handle large data volumes efficiently, while meticulously documenting defects and test results for audit and compliance purposes.

  • Create, modify, and support JCL required for data extracts, file transfers, conversion processing, and migration testing.
  • Perform COBOL program analysis and code modifications to support data extraction, transformation, validation, and reconciliation requirements.
  • Review and update FTP/SFTP processes to support secure transmission of migration files between source and target environments.
  • Utilize IMS utilities and BMC Utilities for IMS to unload, extract, validate, and reconcile database content.
  • Develop and execute data validation and reconciliation procedures to ensure data integrity throughout the migration lifecycle.
  • Support file mapping, field-level transformation logic, and data conversion specifications.
  • Troubleshoot batch failures, abends, data discrepancies, and performance issues related to migration processing.
  • Collaborate with database administrators, architects, business analysts, and project teams to define migration requirements and resolve technical challenges.
  • Create technical documentation, migration runbooks, implementation procedures, and production support documentation.
  • Participate in migration testing, system integration testing, user acceptance testing, and production implementation activities.
  • Provide production support during migration cutover and post-implementation stabilization periods.
  • Identify opportunities for automation using CLIST, REXX, File-AID, and other mainframe utilities.
  • Ensure compliance with enterprise change management, security, and audit requirements.
Qualifications
  • 10+ years of Mainframe Development experience.
  • Expert-level COBOL programming experience.
  • Strong JCL development and troubleshooting skills.
  • Extensive IMS Database experience.
  • Experience with BMC Utilities for IMS.
  • Experience developing large-scale data extracts and conversion processes.
  • Strong understanding of FTP/SFTP file transfer methodologies.
  • Proven experience supporting enterprise data migration or modernization initiatives.
  • Experience performing data analysis, reconciliation, and validation.
  • Ability to work independently with minimal supervision in a deadline-driven environment.
Preferred Qualifications
  • Experience with File-AID.
  • Experience with EZtrieve.
  • Experience with CLIST and REXX automation.
  • Prior experience with legacy modernization or cloud migration projects.
  • Experience supporting financial services, insurance, healthcare, or government mainframe environments.
Critical Success Factors
  • Ability to quickly assess complex legacy environments.
  • Strong problem-solving and troubleshooting capabilities.
  • Excellent communication and documentation skills.
  • Ability to meet aggressive deadlines and deliver high-quality migration solutions under tight timelines.
