How the move works
- 1
Connect Vultr
Connect Vultr with read-only access (API key (personal access token)).
- 2
Connect Oracle Cloud
Connect Oracle Cloud (API signing key (tenancy, user, fingerprint, key)). Write access is only used when you apply.
- 3
Review the preview
Check every record marked Review or Unsupported. Each one explains what changes and why.
- 4
Apply to Oracle Cloud
We snapshot the Oracle Cloud zone, write in batches, and leave Vultr untouched.
- 5
Verify
We query Oracle Cloud's own nameservers for every record and compare the answers before you switch.
- 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 Vultr
- Vultr API keys can't be limited to read-only, so use a dedicated user that only has the Manage DNS permission.
- If API Access Control is enabled, requests from IP addresses that aren't on the allow-list are rejected.
- TXT values can't contain double quotes.
Access we need: A user with the Manage DNS permission for both preview and apply. Vultr keys have no read-only mode.
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 Vultr 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 Vultr?
No. We never write to Vultr. 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.
