Checklist
We review the migration against a structured checklist covering the areas where rebuilds most often go wrong:
- Authentication and session handling — how identity and access actually work
- Authorization — whether users can only reach what they're entitled to
- Data handling — how sensitive data is stored, transmitted and scoped
- Secrets and configuration — where credentials live and how they're protected
- Dependencies and integrations — the third-party surface the product exposes
- Infrastructure and deployment — the boundaries around the running system
