What Is Migration Testing: How to Efficiently Conduct Testing While Migrating Data?
Technology is ever-evolving with new advancements making its presence every day. Organizations are constantly updating their legacy systems to the new ones to take advantage of these developments and align with the constantly changing end-user preferences. However, the major challenge lies in migrating to the new system without losing data. Data owned by organizations is an asset that provides critical insights to plan future endeavors, hence, organizations cannot afford to lose them.
Though data migration is a tedious process that requires enormous effort and time, it is a significant process that plays a crucial role in application redesign. Data migration cannot yield favorable results without a thorough testing process in place. Migration testing ensures that data integrity is maintained while upgrading, integrating, or transferring the system, while making data migration a success that affects your business positively.
Migration testing ensures the data migration has not resulted in any disruption and all functional and non-functional aspects of applications are retained even after migration. It is extremely important to undertake Data Migration Testing to find out the discrepancies that arise while migrating the data from the parent or legacy database to the new or destination database. Organizations must efficiently conduct testing while migrating data for smooth operations.
The need for migration testing
Testing of the system is critical even when the slightest change is made, to ensure the incorporated change doesn’t create any conflict in the current workflow or make any further unnecessary modifications. Hence, it becomes important to carry out end-to-end testing during the system migration process. Migration testing is essential as it:
- Ensures continuity and consistency after the platform migration – imagine if your mortgage computation changed because the lender changed systems?
- Ensures no data loss when you move to the new platform – imagine if your broker could no longer locate your retirement account after her company upgraded their systems?
- It identifies any defects in the new application and ensures that it works perfectly without any issue.
- When migrating from one system to another, migration testing ensures proper flow and working of the application, as it was before migration.
- In addition to testing data retention and functionality checks, migration testing also checks if the application is optimized to the new workflows and environment.
