How to Migrate Domain DNS to Cloudflare with Zero Downtime

Migrating DNS to Cloudflare requires careful attention to TTL values and record verification to ensure zero downtime.

Step 1 — Add Domain to Cloudflare and Verify Records

dig yourdomain.com A
dig yourdomain.com MX
dig yourdomain.com TXT
# Compare all with Cloudflare dashboard

Step 2 — Lower TTL Before Migration

# At current DNS provider — change all TTLs to 300
# Wait 24 hours for reduction to propagate

Step 3 — Important — Mail Records

# Mail records MUST have proxy OFF (grey cloud)
# SSH/FTP records MUST have proxy OFF
# Only HTTP/HTTPS records should have proxy ON

Step 4 — Change Nameservers

Domain registrar → Nameservers → set to Cloudflare nameservers shown in dashboard

Step 5 — Verify

dig NS yourdomain.com
