Safeguard your business through data migration with reconciliation and validation

When migrating data, reconciliation and data validation are not just technical steps—they are critical components that ensure the success and integrity of your business operations. Data reconciliation helps verify that all information has been accurately transferred to the new system, leaving no room for costly errors or data loss.

Skipping or overlooking these processes can lead to flawed insights, operational disruptions, and reputational risks. By prioritising data reconciliation and validation, you safeguard your business and set the foundation for informed decision-making.

Our 5-step data reconciliation and validation process

Reconciliation and validation processes are essential to maintaining data accuracy and demonstration of controls across systems when migrating data. Below are the critical steps we take at Elwyn Consulting to ensure the integrity of your data is maintained during the migration.

Step 1

Compare values field-by-field between the source and target

One of the foundational steps in data reconciliation is performing a detailed comparison of values. This involves examining each field in the source system and comparing it directly with the corresponding field in the target system, focusing on critical fields and key metrics for business operations.

This step is essential for detecting anomalies, errors, or discrepancies that might have occurred during migration. By ensuring field-level accuracy, you can identify and fix mismatches before they become more significant issues.

Step 2

Implement validation checks for completeness and accuracy

Validation checks are non-negotiable for verifying the integrity of your data. Completeness checks confirm that no data was omitted during the migration process, while accuracy checks ensure that every value matches its intended format and context.

Conducting these checks ensures that every record is present and correctly represented in the target system.

Step 3

Maintain consistency across related data

Data ecosystems often rely on relationships between different tables or entities in a database. For example, a customer record in one table might be linked to purchase orders or payment information in related tables.

Consistency checks ensure that these relationships remain intact post-migration. Any discrepancies in related datasets—missing references, orphaned records, or mismatched data points—can severely impact workflows and reporting accuracy.

Step 4

Monitor data flow through the entire pipeline

Data pipelines often consist of several stages, from extraction and transformation to loading into the target system. It’s critical to validate and monitor the flow of data through every step of this pipeline.

This means ensuring data integrity as it passes through transformations, filtering, or cleaning processes. Each component in the pipeline must not only accurately process the data but also maintain compatibility with subsequent stages.

Step 5

Validate the successful loading of all data

Finally, thorough reconciliation requires confirming that all data has been successfully loaded into the target system. Beyond counting records, this step verifies that dependent or linked records have also been fully migrated. Failure to load even a small subset of data can lead to incomplete datasets and downstream issues.
