Limitations with domain aliases
- In the Admin console, you can add a domain alias only to your primary domain. To add a domain alias to a secondary domain, use the Directory API.
- Migration from domain aliases is not supported. Some current Google Workspace customers use domain aliases for their non-primary domains.
