How the move works

  1. 1

    Connect FortiGate

    Connect FortiGate with read-only access (Management URL + REST API admin token (Bearer) + VDOM).

  2. 2

    Connect Bunny

    Connect Bunny (Account API key). 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 Bunny

    We snapshot the Bunny zone, write in batches, and leave FortiGate untouched.

  5. 5

    Verify

    We query Bunny'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 FortiGate

  • FortiGates usually sit on private networks: we only connect if the admin HTTPS interface is exposed on a public address with a valid certificate, because private and internal addresses are refused by design.
  • Only A, AAAA and CNAME records plus MX at the zone apex are supported; wildcards, TXT, SRV and CAA are not, and disabled entries are left untouched.
  • Every change rewrites the zone's whole dns-entry table; we read and merge first so records outside the plan survive, but concurrent edits in the GUI can be overwritten.

Access we need: Admin profile with System → Configuration read for the preview, read/write to apply; restrict the REST API admin with trusted hosts.

Good to know about Bunny

  • Pull Zone, Script and Flatten records, and disabled records, aren't migrated. Redirect records are read as URL redirects to recreate by hand.
  • Records that use smart routing (latency or geolocation) or CDN acceleration are flagged and never changed by us.
  • An apex CNAME is flattened by Bunny, so it can point at any hostname.

Access we need: The account API key has full access. There is no read-only key, so rotate it after the migration.

Questions

Will there be downtime moving from FortiGate to Bunny?

Not if both providers serve the same answers during the switch. The records are copied to Bunny 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 FortiGate?

No. We never write to FortiGate. 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 Bunny and publish its new DS record. The cutover plan walks you through each step.
