DNS Migrations at Scale: Why Automation Tools Fall Short

Cloudflare's auto-scan feature promised to simplify DNS migration, but discovered zero records—exposing why relying solely on automated imports is risky for domain-critical changes. The author's hands-on validation pipeline (combining Namecheap API queries, dig verification, and strict validation gates) demonstrates that large-scale DNS transitions require explicit oversight, not just convenience features. As multi-domain management becomes standard practice, this verification-first approach offers a blueprint for migrating infrastructure safely at scale.
