ClouDNS TransIP

Migrate DNS from ClouDNS to TransIP.

12 record types move as they are. 3 things work differently at TransIP, 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
  • ALIAS
  • TLSA
  • SSHFP
  • NAPTR

Routing policies are flattened

TransIP 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.

TransIP rewrites the whole host list

Every write to TransIP's API replaces all records. We read, merge and write once, so records outside the migration survive.

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 TransIP

    Connect TransIP (Username + API private key (signed JWT), or an access token). 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 TransIP

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

  5. 5

    Verify

    We query TransIP'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 TransIP

  • Every change replaces the domain's full DNS entry list in one request; entries outside the plan are sent back unchanged.
  • The API allows 1000 requests per 15 minutes per account, and access tokens expire after at most one month.
  • TXT values with double quotes, backslashes, backticks or trailing spaces are rejected or altered by TransIP.

Access we need: An API key pair on the account (optionally IP-whitelisted), or a read-only access token for the preview and a read/write token to apply.

Questions

Will there be downtime moving from ClouDNS to TransIP?

Not if both providers serve the same answers during the switch. The records are copied to TransIP 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 TransIP and publish its new DS record. The cutover plan walks you through each step.
