Selectel to Bunny DNS migration differences

Alias records are converted

Selectel alias records become CNAMEs at Bunny. At the apex, Bunny flattens them automatically.

Set up the connections

Use the provider-specific credential guides before you preview, then keep the migration checklist beside the cutover plan.

How the move works

  1. 1

    Connect Selectel

    Connect Selectel with read-only access (Service user (username + password) with a project-scoped IAM token).

  2. 2

    Connect Bunny

    Connect Bunny (Account 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 Bunny

    We snapshot the Bunny zone, write in batches, and leave Selectel untouched.

  5. 5

    Verify

    We query Bunny'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 Selectel

  • Only DNS Hosting (actual) zones are supported. Zones still on DNS Hosting (legacy, API v1) must be moved to the actual version in the control panel first.
  • Zones belong to a project; this connection only sees the project it signs in to.
  • Apex NS and SOA records are created and managed by Selectel and can't be changed.
  • A CNAME can't be placed at the zone apex; use ALIAS instead.
  • Each record set can hold at most 100 values.
  • Records you disabled in Selectel are left untouched and aren't imported.
  • Selectel doesn't publish API rate limits; requests are retried with backoff when throttled.

Access we need: Create a service user with the member role scoped to only the project that holds your zones. The reader role on that project is enough for read-only exports.

Good to know about Bunny

  • Redirect records (BUNNY_DNS_RDR) and Pull Zone records (BUNNY_DNS_PZ, by pull zone ID) are migrated. Script and Flatten records, and disabled records, aren't.
  • A Pull Zone record only works if the pull zone ID exists in the destination bunny.net account.
  • Records that use smart routing (latency or geolocation) or CDN acceleration are flagged and never changed by us.
  • An apex CNAME is flattened by Bunny, so it can point at any hostname.

Access we need: The account API key has full access. There is no read-only key, so rotate it after the migration.

Questions

Will there be downtime moving from Selectel to Bunny?

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

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