How the move works

  1. 1

    Connect Vultr

    Connect Vultr with read-only access (API key (personal access token)).

  2. 2

    Connect Porkbun

    Connect Porkbun (API key + secret API 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 Porkbun

    We snapshot the Porkbun zone, write in batches, and leave Vultr untouched.

  5. 5

    Verify

    We query Porkbun'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 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 Porkbun

  • API Access must be turned on per domain, and only domains registered at Porkbun can be managed.
  • The minimum TTL is 600 seconds and a zone holds at most 2,500 records.
  • URL forwarding is not migrated; the ALIAS/CNAME records Porkbun creates for it are copied as plain records.

Access we need: Porkbun keys have no read-only mode. Restrict the key to the domains you move and turn on API Access for each of them.

Questions

Will there be downtime moving from Vultr to Porkbun?

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