Single Forest AD Sync to Multiple Azure AD

Does anyone have any information on approved architecture for the following:

 

Single AD Forest to two disperate Azure AD Connect instances.  Each synced to different OUs.  Underlying issue is multiple tenants, one AD.  Ultimately would like to be able to sync single AD forest to both tenants, different OUs.  Any direction is appreciated.  

  • Yes, I've done this a few times. So long as the two Azure AD Connect instances are each on different servers, you will be fine. Will any users need to exist in both tenants? That's where things can get sticky.

     Let me know and I can send you some guidelines and starting points

      Microsoft has come a long way in this regards, but we are about to face this exact situation and I see no clear answer as to having two Azure AD Connect syncs look at the same OUs in the same forest.  With the potential for the same user object to exist in both tenants with different domains. Is this possible today?

      Please can you help me for the scenario where a specific OU from AD will be synced to 2 Azure AD tenants. First tenant will have o365 Exchange, Sharepoint, the 2nd tenant will have o365 Power BI.

       

      Users access to o365 from 1st Tenant and Power BI from 2nd Tenant both with MFA.

       

      thanks
