How the move works
- 1
Connect Route 53
Connect Route 53 with read-only access (Cross-account IAM role with an external ID).
- 2
Connect Gigahost
Connect Gigahost (Personal API key (Bearer flux_live_…)). 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 Gigahost
We snapshot the Gigahost zone, write in batches, and leave Route 53 untouched.
- 5
Verify
We query Gigahost'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 Route 53
- Alias records can only target AWS resources or records in the same hosted zone.
- Weighted, latency, geolocation and failover routing are Route 53 features. Most other providers can't reproduce them.
- Apex CNAMEs are not allowed. Use an alias record instead.
Access we need: route53:ListHostedZones, GetHostedZone, ListResourceRecordSets for the preview; ChangeResourceRecordSets and CreateHostedZone to apply.
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.
Questions
Will there be downtime moving from Route 53 to Gigahost?
Not if both providers serve the same answers during the switch. The records are copied to Gigahost 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 Route 53?
No. We never write to Route 53. 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 Gigahost and publish its new DS record. The cutover plan walks you through each step.
