Full Life-cycle Testing / Data Migration Testing

Often underestimated, data migration testing is a critical to the success of many implementations. It is performed to verify that legacy data has been migrated completely and correctly, without loss or duplication.

Data migration testing requires a different and very specific approach and set of tools and techniques to system testing or UAT for example.

• Identify minimum set of test cases to adequately mitigate risk without having to check every record
• Definitions of defect severity appropriate to data migration
• Separate testing of data from functionality allowing the data migration to be tested earlier in the SDLC
  

• Verify data has been migrated completely without loss or duplication
• Verify data mapping and conversion rules have been applied correctly
