What works differently

Generated from the same provider capability data the migration engine uses.

Routing policies are flattened

Exoscale 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

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

How the move works

  1. 1

    Connect Route 53

    Connect Route 53 with read-only access (Cross-account IAM role with an external ID).

  2. 2

    Connect Exoscale

    Connect Exoscale (IAM API key + 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 Exoscale

    We snapshot the Exoscale zone, write in batches, and leave Route 53 untouched.

  5. 5

    Verify

    We query Exoscale'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 Route 53

  • Alias records can only target AWS resources or records in the same hosted zone.
  • Weighted, latency, geolocation and failover routing are Route 53 features. Most other providers can't reproduce them.
  • Apex CNAMEs are not allowed. Use an alias record instead.

Access we need: route53:ListHostedZones, GetHostedZone, ListResourceRecordSets for the preview; ChangeResourceRecordSets and CreateHostedZone to apply.

Good to know about Exoscale

  • Exoscale DNS needs an active DNS subscription on the organization before zones can be created.
  • PTR and TLSA records aren't supported, and SRV records can't have an empty target.
  • Apex NS records are fixed by Exoscale and can't be changed.

Access we need: An IAM role limited to the dns service: read operations for the preview; all dns operations to apply.

Questions

Will there be downtime moving from Route 53 to Exoscale?

Not if both providers serve the same answers during the switch. The records are copied to Exoscale 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 Route 53?

No. We never write to Route 53. 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 Exoscale and publish its new DS record. The cutover plan walks you through each step.
