How the move works
- 1
Connect Gigahost
Connect Gigahost with read-only access (Personal API key (Bearer flux_live_…)).
- 2
Connect Cloudflare
Connect Cloudflare (Scoped API token). Write access is only used when you apply.
- 3
Review the preview
Check every record marked Review or Unsupported. Each one explains what changes and why.
- 4
Apply to Cloudflare
We snapshot the Cloudflare zone, write in batches, and leave Gigahost untouched.
- 5
Verify
We query Cloudflare's own nameservers for every record and compare the answers before you switch.
- 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 Gigahost
- DNSSEC can only be switched on through the API for .no domains registered with Gigahost.
- Null MX records and TXT values with leading or trailing spaces are rejected or trimmed by the API.
- Redirects are separate objects and aren't migrated as DNS records.
Access we need: An API key with DNS read permission for the preview and DNS write to apply, optionally limited to specific zone IDs.
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 Gigahost 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 Gigahost?
No. We never write to Gigahost. 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.
