identifying manager from another forest

Respected Contributor

My client was recently acquired. The new corporation has 2 AD forests, that are syncing accounts to one O365 tenant. Some of the employees have managers from the new firm. What is the recommended best practice for maintaning the Manager attribute in this scenario?


I'm thinking that they should use FIM/MIM with Azure AD Connect, but I don' t know how to do that .
