Hi All,
Is there a way to take convert users that have been synced from AD on-perm using AADSYNC to cloud only users, and to actually cease the AADSYNC altogether.
I appreciate that this is a strange question but the reasons for asking are client / politically driven, rather than technical - I will try to explain below....
Unfortunately, a client we support (750-100 seats) that uses a simple, straightforward on-prem exchange have been brought by a parent company that wants to move them to o365. Sadly, further to this, they want them to be migrated to their existing tenancy, where they have already set up directory syncing with another forest, plus have several of other smaller organisations already on boarded as cloud only users.
The organisation that we are tasked with migrating are substantially larger that anything they have already on boarded onto to tenancy.
Obviously, we would want our client to be synced from on-prem due to their size and best practice guidance from Microsoft - this is impossible to achieve given that there is already a AADSYNC in place.
We need to get to a point where we can begin a "Multiple forests, single Azure AD directory topology" with o365, as described here https://azure.microsoft.com/en-gb/documentation/articles/active-directory-aadconnect-topologies/
In order to do this we need a "neutral" AADSYNC server with access to all of the forests that may need to be synced - which means removing the existing one and creating a new one?
Any advice greatly appreciated.
Ben
