Vercel DNS Oracle Cloud DNS

Migrate DNS from Vercel to Oracle Cloud.

10 record types move as they are. Nothing else needs special handling.

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
  • ALIAS
  • CAA
  • CNAME
  • HTTPS
  • MX
  • NS
  • SRV
  • TXT

A straightforward move.

Every record type Vercel supports has a direct equivalent at Oracle Cloud.

  • ExactAAAA@

    2001:db8::70

  • ExactMX@

    10 mx1.mail.example.net. +1

  • ExactTXT@

  • ExactCAA@

    0 issue "letsencrypt.org"

  • ExactTXT_dmarc

    "v=DMARC1; p=reject; rua=mailto:dmarc@example.com"

  • ExactSRV_sip._tls

    100 1 443 sip.example.net.

  • ExactCNAMEwww

    example.com.

How the move works

  1. 1

    Connect Vercel

    Connect Vercel with read-only access (Access token (+ team ID)).

  2. 2

    Connect Oracle Cloud

    Connect Oracle Cloud (API signing key (tenancy, user, fingerprint, key)). 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 Oracle Cloud

    We snapshot the Oracle Cloud zone, write in batches, and leave Vercel untouched.

  5. 5

    Verify

    We query Oracle Cloud'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 Vercel

  • Records Vercel adds for project domains (such as the apex ALIAS and CAA) are read with a comment and never changed by us. Edit them in the project's domain settings.
  • Domains must already be added to the Vercel account or team. We can't create them.
  • Vercel DNS doesn't support DNSSEC, and the minimum TTL is 60 seconds.

Access we need: An access token scoped to the team that owns the domains. Vercel tokens can't be read-only.

Good to know about Oracle Cloud

  • Only public zones in the commercial realm (oraclecloud.com) are supported. Private resolver zones are skipped.
  • Apex NS records are fixed by Oracle Cloud, and records marked as protected can't be changed.
  • DNSSEC key-signing-key rollovers still need a manual promote step in Oracle Cloud after the DS record is updated at the registrar.

Access we need: An IAM policy with “read dns” for the preview; “manage dns” to apply.

Questions

Will there be downtime moving from Vercel to Oracle Cloud?

Not if both providers serve the same answers during the switch. The records are copied to Oracle Cloud 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 Vercel?

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