How the move works
- 1
Connect Vultr
Connect Vultr with read-only access (API key (personal access token)).
- 2
Connect Cloud DNS
Connect Cloud DNS (Service account key (JSON)). 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 Cloud DNS
We snapshot the Cloud DNS zone, write in batches, and leave Vultr untouched.
- 5
Verify
We query Cloud DNS'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 Cloud DNS
- Routing policies (weighted round robin, geolocation, failover) don't carry over to most providers.
- Apex CNAMEs are not allowed.
Access we need: roles/dns.reader for the preview, roles/dns.admin to apply.
Questions
Will there be downtime moving from Vultr to Cloud DNS?
Not if both providers serve the same answers during the switch. The records are copied to Cloud DNS 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 Cloud DNS and publish its new DS record. The cutover plan walks you through each step.
