Route 53 to Openprovider DNS migration differences

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

Moves as-is

  • A
  • AAAA
  • CNAME
  • MX
  • TXT
  • SRV
  • CAA
  • TLSA
  • SSHFP

Alias records are converted

Route 53 alias records become CNAMEs below the apex. At the apex they need static addresses, and the preview shows which ones.

Routing policies are flattened

Openprovider 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 900s are raised

Openprovider's minimum TTL is 900 seconds. Shorter TTLs are raised to 900s and shown as translated.

A typical Route 53 zone at Openprovider

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

Route 53 Openprovider

  • UnsupportedA@

    Not migrated

    @ is an alias to d1a2b3.cloudfront.net at the zone apex. Openprovider doesn't support apex aliases or CNAMEs.

  • 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.

  • ReviewAapi

    192.0.2.10 +1

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

  • TranslatedTXTlegacy

    "v=spf1 -all"

    SPF record type is obsolete. Stored as TXT, which is what mail servers read.

  • ExactCNAMEwww

    example.com.

Set up the connections

Use the provider-specific credential guides before you preview, then keep the migration checklist beside the cutover plan.

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 Openprovider

    Connect Openprovider (Contact person username and password with API access enabled). 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 Openprovider

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

  5. 5

    Verify

    We query Openprovider'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 Openprovider

  • Openprovider only accepts TTLs of 900, 3600, 10800, 21600, 43200 and 86400 seconds; other TTLs are rounded up to the next accepted value.
  • Apex NS and SOA records are managed by Openprovider. NS records can't be added for subdomains and a CNAME can't sit at the zone apex (no ALIAS/ANAME).
  • Null MX records (target ".") aren't supported. Legacy SPF-type records can be read and removed but not created; use TXT.
  • Sectigo Premium DNS zones aren't listed or changed through this connection.
  • Zones on Openprovider nameservers are signed automatically. For domains on other nameservers, Openprovider registers DNSSEC from the DNSKEY public key, not the DS digest.
  • Identical API calls are limited to 300 per 5 minutes and failed logins to 100 per hour; going over can block the contact's API access until it's unblocked in the control panel.

Access we need: Openprovider API access is switched on per contact person and uses that contact's login; it can't be limited to read-only or to DNS only. Create a dedicated contact person for DNSMigrator and turn its API access off when you're done.

Questions

Will there be downtime moving from Route 53 to Openprovider?

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