Gandi LiveDNS Cloudflare DNS

Migrate DNS from Gandi to Cloudflare.

16 record types move as they are. 2 things work differently at Cloudflare, and the preview shows exactly which of your records they affect.

Free preview. Read-only. Nothing changes until you apply.

What works differently

Generated from the same provider capability data the migration engine uses.

Moves as-is

  • A
  • AAAA
  • CNAME
  • MX
  • TXT
  • NS
  • SRV
  • CAA
  • PTR
  • DS
  • HTTPS
  • SVCB
  • TLSA
  • SSHFP
  • NAPTR
  • LOC

Alias records are converted

Gandi alias records become CNAMEs at Cloudflare. At the apex, Cloudflare flattens them automatically.

How the move works

  1. 1

    Connect Gandi

    Connect Gandi with read-only access (Personal access token (legacy API key also accepted)).

  2. 2

    Connect Cloudflare

    Connect Cloudflare (Scoped API token). Write access is only used when you apply.

  3. 3

    Review the preview

    Check every record marked Review or Unsupported. Each one explains what changes and why.

  4. 4

    Apply to Cloudflare

    We snapshot the Cloudflare zone, write in batches, and leave Gandi untouched.

  5. 5

    Verify

    We query Cloudflare's own nameservers for every record and compare the answers before you switch.

  6. 6

    Switch nameservers

    Lower TTLs a day or two ahead, remove any DS record if DNSSEC is on, then point the domain at the new nameservers at your registrar.

Good to know about Gandi

  • LiveDNS only hosts zones for domains in your Gandi organization, so zones can't be created for domains registered elsewhere.
  • ALIAS records are only allowed at the zone apex; TTLs must be between 300 seconds and 30 days.
  • Apex NS records are managed by Gandi and are left untouched.

Access we need: A token with “Manage domain name technical configurations”, scoped to the domains you move. Gandi has no read-only LiveDNS permission.

Good to know about Cloudflare

  • Proxied (orange-cloud) records hide the origin IP. Moving them to another provider sends traffic straight to the origin.
  • Apex CNAMEs are flattened by Cloudflare. Other providers need an ALIAS record or static A/AAAA records instead.
  • Cloudflare Registrar only allows Cloudflare nameservers, so domains registered there must be transferred out first.

Access we need: Zone → DNS → Read for the preview, Zone → DNS → Edit to apply.

Questions

Will there be downtime moving from Gandi to Cloudflare?

Not if both providers serve the same answers during the switch. The records are copied to Cloudflare and verified before you change nameservers, so resolvers get the same answer from either side while caches expire.

Do I have to delete anything at Gandi?

No. We never write to Gandi. Keep the old zone for a week after cutover so you can switch back instantly if anything looks wrong.

What about DNSSEC?

If DNSSEC is on, remove the DS record at your registrar and wait for it to expire before switching nameservers. Then enable DNSSEC at Cloudflare and publish its new DS record. The cutover plan walks you through each step.
