Description: Data Migration Testing is a set of procedures designed to ensure that data is accurately and completely transferred from one system to another. This process is crucial in the implementation of new software systems, where data integrity and quality are fundamental for the proper functioning of the new environment. During these tests, it is verified that the migrated data maintains its structure, format, and relationships, as well as ensuring that no information is lost in the process. Tests may include comparing records before and after migration, validating data in the new system, and performing performance tests to ensure that the system can handle the data load. The importance of these tests lies in the fact that a failed data migration can result in significant information loss, affecting the organization’s operations and its ability to make decisions based on accurate data. Therefore, Data Migration Testing is an essential part of the software development life cycle, ensuring that transitions between systems are smooth and trouble-free.
