Indium Software outlines a migration testing strategy focused on early defect detection to enhance software quality. The document contrasts traditional post-migration testing with a new pre-migration approach, highlighting benefits such as reduced defects, risk, and costs. This strategy aims to ensure compatibility and functionality while increasing efficiency and transparency in the migration process.

Traditional Migration Testing
Migrations have been tested as a form of post-migration testing.
Post-Migration Testing
 Performed once the migration is completed
 The sum of errors identified are very significant
Disadvantages
 Testing to start relatively late in the overall process
 Labour intensive and causes many data-level errors

A New Migration Testing Strategy
Pre-Migration Testing
 Testing takes place prior to the actual migration of any data, including test migrations
Pre-migration testing will assist in
 Defect Detection in Early Phase
 Risk Reduction
 Cost –Effectiveness
 Migration is released with zero defects
 Less challenges during production migration

Cost Reduction
 Early Defect leads to low cost
 Earlier a defect is found/fixed, the cost is less
 Overall Cost is reduced in Pre-Migration testing.
