PowerDNS Authoritative DNSimple

Migrate DNS from PowerDNS to DNSimple.

17 record types move as they are. 2 things work differently at DNSimple, 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.

How the move works

  1. 1

    Connect PowerDNS

    Connect PowerDNS with read-only access (API URL + API key (X-API-Key) + server ID).

  2. 2

    Connect DNSimple

    Connect DNSimple (Account API access token). 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 DNSimple

    We snapshot the DNSimple zone, write in batches, and leave PowerDNS untouched.

  5. 5

    Verify

    We query DNSimple'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 PowerDNS

  • We only connect to public HTTPS addresses: expose the PowerDNS webserver through a reverse proxy with TLS and allow-list our egress IPs; private or internal addresses are refused.
  • ALIAS records only resolve if expand-alias and a resolver are configured on the server, and DNAME needs dname-processing.
  • Disabled records are not imported, and an RRset we update is replaced as a whole, so disabled entries inside it are dropped.

Access we need: The PowerDNS API key grants full read/write access to every zone on the server; there is no read-only key. Restrict it with webserver-allow-from.

Good to know about DNSimple

  • Add the domain to your DNSimple account before migrating; zones can't be created through this connection.
  • Apex NS and SOA records are managed by DNSimple and can't be changed.
  • ALIAS, URL and some record types depend on your DNSimple plan.

Access we need: DNSimple tokens can't be limited to read-only. Use an account token (not a user token) so access is confined to one account.

Questions

Will there be downtime moving from PowerDNS to DNSimple?

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

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