ClouDNS Tencent Cloud DNSPod

Migrate DNS from ClouDNS to DNSPod.

9 record types move as they are. 4 things work differently at DNSPod, and the preview shows exactly which of your records they affect.

Free preview. Read-only. Nothing changes until you apply.

What works differently

Generated from the same provider capability data the migration engine uses.

Moves as-is

  • A
  • AAAA
  • CNAME
  • MX
  • TXT
  • NS
  • SRV
  • CAA
  • SPF

Alias records are converted

ClouDNS alias records become CNAMEs below the apex. At the apex they need static addresses, and the preview shows which ones.

Routing policies are flattened

DNSPod has no routing policies. Weighted, geo and latency sets collapse into one set of answers, and failover keeps only the primary. Each one is flagged for review.

TTLs below 600s are raised

DNSPod's minimum TTL is 600 seconds. Shorter TTLs are raised to 600s and shown as translated.

ClouDNS DNSPod

  • TranslatedA@

    192.0.2.70

    TTL 300s is outside the allowed range. Set to 600s.

  • TranslatedAAAA@

How the move works

  1. 1

    Connect ClouDNS

    Connect ClouDNS with read-only access (API user auth ID (or sub-user ID/name) + password).

  2. 2

    Connect DNSPod

    Connect DNSPod (CAM SecretId + SecretKey). 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 DNSPod

    We snapshot the DNSPod zone, write in batches, and leave ClouDNS untouched.

  5. 5

    Verify

    We query DNSPod'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 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.

Good to know about DNSPod

  • DNSSEC and DS records are managed in the DNSPod console; the API can't change them.
  • The minimum TTL depends on the DNSPod plan: 600 seconds on the free plan, lower on paid plans.
  • China-site and International-site accounts use different API endpoints; pick the matching site.
  • Records on non-default resolution lines (ISP or region routing) are read as geo-routed records.

Access we need: QcloudDNSPodReadOnlyAccess for the preview, QcloudDNSPodFullAccess (or a custom dnspod:* write policy) to apply.

Questions

Will there be downtime moving from ClouDNS to DNSPod?

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

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