Sakura Cloud DNS Namecheap BasicDNS

Migrate DNS from Sakura Cloud to Namecheap.

8 record types move as they are. 4 things work differently at Namecheap, 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
  • CAA
  • ALIAS

TTLs below 60s are raised

Namecheap's minimum TTL is 60 seconds. Shorter TTLs are raised to 60s and shown as translated.

Namecheap rewrites the whole host list

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

Namecheap needs BasicDNS turned on

Namecheap only accepts records while the domain uses its BasicDNS nameservers, so records are written at cutover time rather than staged in advance.

  • ExactTXT_dmarc

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

    Namecheap doesn't support SRV records through its API.

  • ExactCNAMEwww

    example.com.

How the move works

  1. 1

    Connect Sakura Cloud

    Connect Sakura Cloud with read-only access (API key (access token + access token secret)).

  2. 2

    Connect Namecheap

    Connect Namecheap (API user + API key, with our egress IP allow-listed). 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 Namecheap

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

  5. 5

    Verify

    We query Namecheap'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 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.

Good to know about Namecheap

  • Namecheap's API replaces the whole host list on every write, so we always read, merge and then write.
  • SRV records can't be managed through the API.
  • URL redirect records are Namecheap-specific and aren't real DNS records.

Access we need: API access enabled under Profile → Tools, with our static IP added to the allow-list.

Questions

Will there be downtime moving from Sakura Cloud to Namecheap?

Not if both providers serve the same answers during the switch. The records are copied to Namecheap 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 Sakura Cloud?

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