Ad Local to azure Ad via ad azure connect

Copper Contributor


here is the scenario, I have a customer who has a local ad and has been using since 1 year o365.
it uses exchange/sharpoint/OneDrive...
Today he wants to synchronize his local AD with Ad azure d'office 365, and set up a single authentication.

The quesion is simple can we do this synchronization? my fear and that it will delete the existing users so the data.


Best Regards,
