ClouDNS Joker.com

Migrate DNS from ClouDNS to Joker.

9 record types move as they are. 5 things work differently at Joker, 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
  • NAPTR

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

Joker 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 300s are raised

Joker's minimum TTL is 300 seconds. Shorter TTLs are raised to 300s and shown as translated.

Joker rewrites the whole host list

Every write to Joker'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 Joker

    Connect Joker (DMAPI API key (or username + password), session-based). 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 Joker

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

  5. 5

    Verify

    We query Joker'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 Joker

  • Joker replaces the whole zone on every write, so we read, merge and write it; URL, frame, mail-forward and DynDNS entries we don't change are kept as they are.
  • TTLs must be at least 300 seconds (NAPTR excepted), and apex NS records are managed by Joker.
  • TXT values can't contain backslashes or unpaired double quotes.

Access we need: A dedicated DMAPI API key; DMAPI has no DNS-only scope, so revoke the key after the move.

Questions

Will there be downtime moving from ClouDNS to Joker?

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