Migrate Custom Domains without Downtime

Overview

This article explains if it is possible to migrate a custom domain (as in rebranding) without the normal downtime that would result from deleting the current domain and configuring a new domain.

Applies To

  • Custom Domains
  • Domain Migration

Cause

Previously, downtime was inevitable when migrating to a new custom domain because a tenant could have a single custom domain. The old, existing custom domain had to be deleted before configuring the new one.

Solution

Auth0 can now enable a flag that temporarily allows multiple custom domains in one tenant.

Note that the flag is not intended to allow for multiple custom domains in perpetuity.

Please reach out to support with the following information:

  • Tenant name
  • Expected testing and migration time window
