How the move works
- 1
Connect deSEC
Connect deSEC with read-only access (API token).
- 2
Connect Exoscale
Connect Exoscale (IAM API key + secret). 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 Exoscale
We snapshot the Exoscale zone, write in batches, and leave deSEC untouched.
- 5
Verify
We query Exoscale'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 deSEC
- The minimum TTL is 3600 seconds for most domains (deSEC sets it per domain) and the maximum is 86400.
- ALIAS/ANAME records and apex CNAMEs aren't supported; use A/AAAA or HTTPS records at the apex.
- Every zone is DNSSEC-signed automatically. Give the DS records to your registrar to complete the chain.
Access we need: Any token can read all RRsets. Applying needs write permission on the RRsets (token policies can restrict it); creating zones needs perm_create_domain.
Good to know about Exoscale
- Exoscale DNS needs an active DNS subscription on the organization before zones can be created.
- PTR and TLSA records aren't supported, and SRV records can't have an empty target.
- Apex NS records are fixed by Exoscale and can't be changed.
Access we need: An IAM role limited to the dns service: read operations for the preview; all dns operations to apply.
Questions
Will there be downtime moving from deSEC to Exoscale?
Not if both providers serve the same answers during the switch. The records are copied to Exoscale 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 deSEC?
No. We never write to deSEC. 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 Exoscale and publish its new DS record. The cutover plan walks you through each step.
