Migration Validator Skill Skill

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
