How the move works
- 1
Connect CentralNic
Connect CentralNic with read-only access (Reseller (or sub-user) login + password over the HTTPS gateway).
- 2
Connect ClouDNS
Connect ClouDNS (API user auth ID (or sub-user ID/name) + password). 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 ClouDNS
We snapshot the ClouDNS zone, write in batches, and leave CentralNic untouched.
- 5
Verify
We query ClouDNS'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 CentralNic
- Creating a KeyDNS zone can incur a charge on your reseller account.
- ALIAS records only work on unsigned zones; they can't be used with DNSSEC signing.
- Web and mail forwards are separate objects in the API and aren't migrated as DNS records.
Access we need: A sub-user allowed QueryDNSZoneList, QueryDNSZoneRRList and StatusDNSZone for the preview; ModifyDNSZone (and AddDNSZone to create zones) to apply.
Good to know about ClouDNS
- TTLs must be one of ClouDNS's fixed values (60, 300, 900, 1800, 3600, 21600 … 2592000); other TTLs are rounded up.
- Web redirects (CLOUDNS_WR) are ClouDNS-only and are written as plain 301 redirects without frame options.
- The API is rate limited to about 20 requests per second per IP, so large zones apply record by record and take a while.
Access we need: A read-only API sub-user with the zones delegated is enough for the preview; applying needs a read-and-write sub-user or a main API user.
Questions
Will there be downtime moving from CentralNic to ClouDNS?
Not if both providers serve the same answers during the switch. The records are copied to ClouDNS 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 CentralNic?
No. We never write to CentralNic. 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 ClouDNS and publish its new DS record. The cutover plan walks you through each step.
