Sync ADFS with new and old Domain RRS feed

  • Question

  • Hi All, 

    We are in the process of setting up a new server environment for one of clients replacing their old system. What we are planning is to have both network running side by side so we can do some proper testing before we go live. What we need help with is ADFS sync to office 365. They use single sign on for office on the system. 

    Is it possible to have ADFS sync with both domains at the same time? Domain name is new, but the UPN`s and so on will be exactly the same on both sides.

  • Hello,

    ADFS is not used for "sync", it is used for authentication (Azure AD Connect is used for synchronization).

    As far as I know, an Office 365 domain can only be federated once, so only one ADFS environment can be used.
