Centralize Azure Active Directories

Hi,

I have a Office 365 tenant, and 3 Azure Active Directories: Prod,PreProd, Dev,

I have also a on-premise AD.

As i cannot federate my domain with all environment in cloud (off365, AAD prod, AAD preprod and AAD dev), I have to centralize my accounts in one AAD  (Ex: Prod) and connect the others AAD and Office 365 to this central repository.

The Central AAD ( Prod) will be Sunchronized and federated (ADFS) with my on-premise AD

I can connect my AAD to Office365, but I need a connection in the other sens: use Synchroinzed accounts to Prod AAD in Office 365.

My question, if it'S possible to implement this scenario where all environments are connected to a central AAD who will be provisioned from on-premise AD .

Thanks

Lourh
