📚 About DNS Migration
When migrating your domain to a new DNS provider, it's critical to ensure all DNS records are properly configured on the new nameserver before updating your domain's NS records at the registrar.
Migration Checklist
- 1. Lower TTL values — Reduce TTL to 300-600 seconds 24-48 hours before migration
- 2. Copy all records — Ensure A, AAAA, MX, TXT (including SPF), CNAME, and other records match
- 3. Verify with this tool — Use DNS Nameserver Compare to confirm records match
- 4. Update NS records — Change nameservers at your registrar
- 5. Monitor propagation — Use our DNS Propagation Checker
