Single AD to multi AAD



A company is splitting into smaller companies and each new smaller company wants to have own AAD.

I would lke to know if it's possible to have this scenario:

Is it possible so use hybrid sych users/computers from single AD "" to different AAD (, etc.)?

At the end we will need to have 5 different AAD(those will have cross tenant access in Intra) and those will be hybrid synched for next 2 years -> after that we move to azure only (cloud only)


I need to create new on premise AD -> copy/move users to new AD and turn on AAD sych from new AD ?

    The supported topologies are listed here:

    As long as you are in line with the requirements/restrictions listed in the article above, you can use the 1:many scenario.

    If you plan to split the AD eventually, you might as well do it now, as an alternative.
