Azure DNS Sakura Cloud DNS

Migrate DNS from Azure DNS to Sakura Cloud.

9 record types move as they are. 2 things work differently at Sakura Cloud, 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.

Moves as-is

  • A
  • AAAA
  • CNAME
  • MX
  • TXT
  • NS
  • SRV
  • CAA
  • PTR

TTLs below 10s are raised

Sakura Cloud's minimum TTL is 10 seconds. Shorter TTLs are raised to 10s and shown as translated.

Sakura Cloud rewrites the whole host list

Every write to Sakura Cloud's API replaces all records. We read, merge and write once, so records outside the migration survive.

A typical Azure DNS zone at Sakura Cloud

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

Azure DNS Sakura Cloud

  • UnsupportedA@

    Not migrated

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

  • ExactMX@

    10 mx1.mail.example.net. +1

  • ExactTXT@

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

  • ExactCAA@

    0 issue "letsencrypt.org"

  • 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 Sakura Cloud

    Connect Sakura Cloud (API key (access token + access token secret)). 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 Sakura Cloud

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

  5. 5

    Verify

    We query Sakura Cloud'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 Sakura Cloud

  • Every record with the same name must share one TTL, and a zone can hold at most 2,000 records.
  • TXT values are limited to 500 characters of letters, digits, spaces and _ = : ; ~ , - . + / (no quotes or backslashes), and CAA records to 64 characters.
  • DNSSEC isn't supported, and each write replaces the zone's whole record list, so changes are applied in one request.

Access we need: An API key with the Resource view access level for the preview; Settings edit to apply changes; Create/delete to create (billable) zones.

Questions

Will there be downtime moving from Azure DNS to Sakura Cloud?

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