Azure DNS UniFi Network

Migrate DNS from Azure DNS to UniFi.

6 record types move as they are. 1 things work differently at UniFi, 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.

A typical Azure DNS zone at UniFi

Example records for example.com. Open any flagged row to read why it changed.

Azure DNS UniFi

  • UnsupportedA@

    Not migrated

    @ is an alias to an Azure resource. It needs static IP addresses at UniFi.

  • ExactMX@

    10 mx1.mail.example.net. +1

  • ExactTXT@

    "v=spf1 include:_spf.example.net -all"

  • UnsupportedCAA@

    Not migrated

    UniFi doesn't support CAA records through its API.

  • ExactTXT_dmarc

    "v=DMARC1; p=reject; rua=mailto:dmarc@example.com"

  • ExactSRV_sip._tls

    100 1 443 sip.example.net.

  • ExactAapp

    192.0.2.30

  • ExactCNAMEwww

    example.com.

How the move works

  1. 1

    Connect Azure DNS

    Connect Azure DNS with read-only access (Service principal (client ID + secret)).

  2. 2

    Connect UniFi

    Connect UniFi (API key (X-API-Key) + controller URL or UniFi console ID (via api.ui.com)). 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 UniFi

    We snapshot the UniFi zone, write in batches, and leave Azure DNS untouched.

  5. 5

    Verify

    We query UniFi'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 Azure DNS

  • Azure alias records point at Azure resource IDs, which don't exist outside Azure.
  • Apex CNAMEs are not allowed. Use an alias record to an Azure resource or A/AAAA records.

Access we need: Reader on the DNS zone for the preview, DNS Zone Contributor to apply.

Good to know about UniFi

  • Consoles usually sit on a private network; we refuse private addresses by design, so either use the console ID (reached through api.ui.com) or expose the console publicly over HTTPS.
  • A publicly trusted TLS certificate is required when connecting directly: we never skip certificate verification, so the console's default self-signed certificate will not work.
  • Records are one flat list per site (no zones); only A, AAAA and CNAME have a configurable TTL, and TXT values are limited to 255 characters without double quotes.

Access we need: A UniFi API key acts with the role of the admin who created it; create it from an admin limited to network settings where possible. It can read and write static DNS entries.

Questions

Will there be downtime moving from Azure DNS to UniFi?

Not if both providers serve the same answers during the switch. The records are copied to UniFi 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 Azure DNS?

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