A Data Migration Audit ensures your business critical information transfers securely, accurately, and without compliance failures from legacy systems to new environments. Our service prevents data loss, reduces downtime, and verifies every data point matches its target configuration before go-live.

Our Core Audit Phases

We implement a rigorous, step-by-step validation methodology to guarantee data integrity across your entire system lifecycle.

1. Pre-Migration Data Profiling & Assessment Before any data is moved, we establish a comprehensive baseline to identify risks and determine the exact scope of your migration.
• Source System Analysis: Cataloging all databases, formats, volumes, and custom attributes.
• Data Cleansing: Identifying duplicate, corrupted, or outdated records to prevent transferring "bad data".
• Compliance Check: Ensuring the data transfer adheres to privacy laws like GDPR and HIPAA.
2. Mapping & Transformation Validation
We meticulously review how source system data aligns with your target environment.
• Rule Verification: Checking mapping logic for format changes, truncations, and business logic.
• Data Type Auditing: Ensuring no loss of precision during field conversions.
• Dependency Mapping: Securing relational databases and inter-table dependencies.
3. Post-Migration Reconciliation (Re-Verification)
Once the data is loaded into the new environment, we execute targeted reconciliations to confirm absolute accuracy.
• Count & Volume Reconciliation: Verifying that total row counts and storage volumes match between source and target systems.
• Sample Testing: Running targeted queries on financial, master, and transactional data.
• Error Logging: Reviewing execution logs to resolve anomalies in real time.
