Constellix to deSEC DNS migration differences

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

Moves as-is

  • A
  • AAAA
  • CNAME
  • MX
  • TXT
  • NS
  • SRV
  • CAA
  • PTR
  • NAPTR
  • SPF
  • CERT
  • RP

Alias records are converted

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

TTLs below 3600s are raised

deSEC's minimum TTL is 3600 seconds. Shorter TTLs are raised to 3600s and shown as translated.

Set up the connections

Use the provider-specific credential guides before you preview, then keep the migration checklist beside the cutover plan.

How the move works

  1. 1

    Connect Constellix

    Connect Constellix with read-only access (API key + secret key (HMAC-signed requests)).

  2. 2

    Connect deSEC

    Connect deSEC (API 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 deSEC

    We snapshot the deSEC zone, write in batches, and leave Constellix untouched.

  5. 5

    Verify

    We query deSEC'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 Constellix

  • Records using failover, traffic pools, IP filters, GeoProximity or regional answers are flagged and never changed by us; only the default answer is copied.
  • HINFO records and DNSSEC aren't available through the Constellix v4 API.
  • HTTP redirection records map to URL forwards for the whole hostname (301, 302 or frame); page title and keywords of frame redirects aren't copied.
  • CAA records only support the issue, issuewild and iodef tags.
  • Requests are signed with the current time, so the server clock must be accurate.

Access we need: Constellix API keys carry the permissions of the user who generated them and can't be limited to read-only. Generate them under a user that only manages the domains you're moving.

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.

Questions

Will there be downtime moving from Constellix to deSEC?

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

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