  3. Notify the following three groups of the new subdomain and the planned changes:
    • IT/Network Administrators to update the Single Sign-on settings, specifically new hostnames for metadata, login, logout, validate, and other URLs. In addition, you will use the new subdomain for the entity ID.
    • Third-party Payment Providers, if not using Slate Payments, to notify them of new hostnames for postback, checkout, and other URLs.
    • Web/Marketing to update links on your institutional sites to use the new subdomain.
  4. Submit a request to the Domain and SSO Configuration category with the following information:
      • The new subdomain
      • The intended launch date for the new subdomain
    • Technolutions respond to confirm the details and begin the changeover process.
  5. Once the new domain is up, you can reach out to the groups from step three and let them know to make the appropriate updates. NOTE: The existing subdomain will remain active until the SSL certificate expires (typically about a month after the change). This is designed to ensure that existing links will not immediately expire and give your various campus colleagues time to make the abovementioned changes.
