Key considerations and best practices summary
- Plan meticulously: Do not rush the planning and preparation phases.
- Communicate clearly: Keep stakeholders informed.
- Lower TTLs in advance: This is crucial for a faster cutover.
- Disable DNSSEC before NS change (safest): Remove DS records at the registrar well before changing nameservers, then re-enable DNSSEC via Cloudflare.
- Verify, verify, verify: Double-check record imports and functionality at each stage.
- Test thoroughly: From multiple locations and for all critical services.
- Have a rollback plan: Know how to revert if necessary.
- Migrate during low traffic: Minimize potential user impact.
- Address BIND Views/ACLs: Understand how Cloudflare will handle or replace this functionality.
- Take advantage of Cloudflare features: Once stable, explore and implement Cloudflare's security and performance enhancements.
By following these best practices, you can significantly increase the likelihood of a smooth and successful migration from your on-prem BIND DNS to Cloudflare.
