Google Cloud DNS Scaleway Domains and DNS

Migrate DNS from Cloud DNS to Scaleway.

13 record types move as they are. 3 things work differently at Scaleway, 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
  • HTTPS
  • SVCB
  • TLSA
  • SSHFP
  • NAPTR

Routing policies are flattened

Scaleway has no routing policies. Weighted, geo and latency sets collapse into one set of answers, and failover keeps only the primary. Each one is flagged for review.

TTLs below 60s are raised

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

Cloud DNS Scaleway

  • ExactA@

    192.0.2.40

  • ExactMX@

    10 mx1.mail.example.net. +1

  • ExactTXT@

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

    100 1 443 sip.example.net.

  • ReviewAeu

    192.0.2.41 +1

    Geo routing isn't available at the destination. All 2 answers are served together as simple round-robin.

  • ExactCNAMEwww

    example.com.

How the move works

  1. 1

    Connect Cloud DNS

    Connect Cloud DNS with read-only access (Service account key (JSON)).

  2. 2

    Connect Scaleway

    Connect Scaleway (IAM API secret key (+ optional project ID)). 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 Scaleway

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

  5. 5

    Verify

    We query Scaleway'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 Cloud DNS

  • Routing policies (weighted round robin, geolocation, failover) don't carry over to most providers.
  • Apex CNAMEs are not allowed.

Access we need: roles/dns.reader for the preview, roles/dns.admin to apply.

Good to know about Scaleway

  • Zones must already exist in the Scaleway console. We can't create them.
  • Records that use GeoIP, weighted, HTTP-service or view routing are copied as their default value, flagged in a comment and never changed by us.
  • NS records below the apex need a TTL of at least 1800 seconds, so shorter TTLs are raised.

Access we need: An IAM policy with DomainsDNSReadOnly for the preview; DomainsDNSFullAccess to apply.

Questions

Will there be downtime moving from Cloud DNS to Scaleway?

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

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