UltraDNS (DigiCert)

Migrate DNS zones to or from UltraDNS (DigiCert): what's supported, what access you need, and what changes for each destination.

See how a domain's records would land at UltraDNS. Free and read-only.

Access we need

Credentials
API user name and password (OAuth password grant)
Permissions
Create a dedicated API-only user in a group limited to DNS operations (the built-in TECHNICAL group, or a custom group with DNS read and write). A REPORTING or ungrouped user is enough for a read-only preview. The REST API doesn't support multi-factor login, so MFA must be off for this user.

What UltraDNS supports

The same data the translation engine uses when it plans a migration.

Create zones through the API

Apex CNAME (flattening)

Good to know

  • Traffic-management pools (SiteBacker, Traffic Controller, Directional and Simple Load Balancing) are copied as plain answers and flagged; we never change or delete them on UltraDNS.
  • Resource Distribution pools keep their pool settings when we update their answers.
  • ALIAS is written as UltraDNS Apex Alias, which only works at the zone apex, can't coexist with both A and AAAA at the apex, and can't be used in statically signed zones.
  • SOA, apex NS and system-generated records (such as Valimail DMARC records) are managed by UltraDNS and left untouched.
  • Web Forwards and secondary or alias zones aren't migrated; secondary and alias zones are read-only.
  • UltraDNS locks an account after repeated failed logins, so double-check the password before retrying.
