Azure AD connect is a new tool which replaces DirSync for syncing Active Directory information to Azure from the local active directory.
Synchronisation automatically works in the background, but sometimes you want to push through a synchronisation for some reason or another (rather than waiting for the next time it runs). This can be done by running the following 2 commands from the C:\Program Files\Microsoft Azure AD Sync\bin directory:
DirectorySyncClientCmd.exe initial DirectorySyncClientCmd.exe delta
- initial – this forces a full sync
- delta – this forces a delta sync
