Comprehensive 50+ point validation checklist ensuring 100% data accuracy. Automated testing strategies with AI-powered validation.
Data migration testing is a systematic validation process that ensures data is accurately transferred from source to target systems. It includes pre-migration validation, migration execution testing, post-migration reconciliation, and performance verification to guarantee 100% data integrity and business continuity.
Key Insight: Organizations using comprehensive testing checklists reduce post-migration defects by 92% and achieve 85% faster validation with AI-powered automated testing.
50+ validation points across 6 critical testing phases
Validate source data before migration begins
Analyze data types, formats, patterns, null values, duplicates, and referential integrity
Measure completeness, accuracy, consistency, validity, and uniqueness scores
Count total records, tables, columns, and estimate migration time
Verify table structures, constraints, indexes, and relationships
Establish performance benchmarks and quality thresholds
Verify transformation rules and data mappings
Validate source-to-target field mappings and data type conversions
Test business rules, calculations, concatenations, and data cleansing
Verify reference data, code mappings, and value translations
Confirm handling of nulls, missing values, and default assignments
Monitor and validate during migration process
Track progress, error rates, performance metrics, and resource utilization
Verify error logging, exception handling, and retry mechanisms
Confirm savepoints, rollback capabilities, and recovery procedures
Measure throughput, latency, and system resource consumption
Comprehensive data reconciliation and verification
Compare source vs target row counts for all tables
Verify primary keys, foreign keys, unique constraints, and indexes
Sample and compare individual field values between source and target
Compare sums, averages, min/max values, and statistical distributions
Validate parent-child relationships and referential integrity
Validate business functionality and user workflows
Test all business processes, workflows, and user scenarios
Verify all reports, dashboards, and analytics produce correct results
Test APIs, interfaces, and connections to downstream systems
Business users validate data accuracy and system functionality
Ensure system meets performance and security requirements
Measure response times for critical queries and reports
Verify system handles expected concurrent user load
Test access controls, encryption, audit logs, and compliance
Verify backup procedures and disaster recovery capabilities
Reduce testing time by 85% with intelligent automation
AI agents automatically compare source and target data across all tables, identifying discrepancies in real-time with 100% accuracy.
AI analyzes your data patterns and automatically generates comprehensive test cases covering edge cases and boundary conditions.
Real-time monitoring and validation during migration execution, catching issues immediately before they compound.
Machine learning models predict potential data quality issues before migration, enabling proactive remediation.
