How the move works
- 1
Connect Sakura Cloud
Connect Sakura Cloud with read-only access (API key (access token + access token secret)).
- 2
Connect Cloudflare
Connect Cloudflare (Scoped API token). Write access is only used when you apply.
- 3
Review the preview
Check every record marked Review or Unsupported. Each one explains what changes and why.
- 4
Apply to Cloudflare
We snapshot the Cloudflare zone, write in batches, and leave Sakura Cloud untouched.
- 5
Verify
We query Cloudflare's own nameservers for every record and compare the answers before you switch.
- 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 Cloudflare
- Proxied (orange-cloud) records hide the origin IP. Moving them to another provider sends traffic straight to the origin.
- Apex CNAMEs are flattened by Cloudflare. Other providers need an ALIAS record or static A/AAAA records instead.
- Cloudflare Registrar only allows Cloudflare nameservers, so domains registered there must be transferred out first.
Access we need: Zone → DNS → Read for the preview, Zone → DNS → Edit to apply.
Questions
Will there be downtime moving from Sakura Cloud to Cloudflare?
Not if both providers serve the same answers during the switch. The records are copied to Cloudflare 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 Cloudflare and publish its new DS record. The cutover plan walks you through each step.
