Akamai Edge DNS OVHcloud DNS

Migrate DNS from Akamai to OVHcloud.

16 record types move as they are. 2 things work differently at OVHcloud, 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
  • PTR
  • HTTPS
  • SVCB
  • TLSA
  • SSHFP
  • NAPTR
  • LOC
  • RP

Alias records are converted

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

How the move works

  1. 1

    Connect Akamai

    Connect Akamai with read-only access (EdgeGrid API client (host, client token, client secret, access token)).

  2. 2

    Connect OVHcloud

    Connect OVHcloud (Application key + application secret + consumer key (EU, CA or US API)). 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 OVHcloud

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

  5. 5

    Verify

    We query OVHcloud'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 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.

Good to know about OVHcloud

  • OVHcloud reads each record with a separate API call, so large zones take a while to load.
  • Changes are published when the zone is refreshed, which we trigger after applying; it can take a few minutes.
  • TXT values can't contain double quotes or backslashes, and ALIAS records aren't supported.

Access we need: GET /domain/zone and GET /domain/zone/* for the preview; POST, PUT and DELETE on /domain/zone/* to apply.

Questions

Will there be downtime moving from Akamai to OVHcloud?

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

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