Migration Validator

Migration Validator Skill

Validates functional equivalence between source and target systems after migration through comprehensive comparison and behavioral verification.

Purpose

Enable migration validation for:

• Side-by-side comparison
• Output diffing
• Behavioral verification
• Data consistency checking
• Acceptance criteria verification

Capabilities

1. Side-by-Side Comparison

• Run parallel requests
• Compare responses
• Track differences
• Document discrepancies

2. Output Diffing

• Compare API responses
• Diff file outputs
• Check data formats
• Validate transformations

3. Behavioral Verification

• Test user flows
• Verify business logic
• Check edge cases
• Validate error handling

4. Data Consistency Checking

• Compare data states
• Verify calculations
• Check relationships
• Validate constraints

5. Integration Validation

• Test external integrations
• Verify API contracts
• Check message flows
• Validate events

6. Acceptance Criteria Verification

• Check feature completeness
• Verify requirements
• Validate user stories
• Document coverage
