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 Akamai

    Connect Akamai (EdgeGrid API client (host, client token, client secret, 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 Akamai

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

  5. 5

    Verify

    We query Akamai'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 Akamai

  • AKAMAICDN and non-DUAL AKAMAITLC records point at Akamai edge hostnames. Other providers have no equivalent, so recreate them as CNAME or ALIAS records by hand.
  • Apex ALIAS records are stored as AKAMAITLC records with the DUAL answer type. ALIAS records below the apex become CNAMEs.
  • TXT values can't contain double quotes or backslashes.

Access we need: DNS—Zone Record Management API: READ-ONLY for the preview, READ-WRITE to apply.

Questions

Will there be downtime moving from Constellix to Akamai?

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