About Azure AD Connect

Azure AD Connect is the replacement of Dir Sync, and it is a synchronization engine that sync local Active Directory objects (users, Group and computers) to Microsoft Azure and Office 365.

The reason companies are using syncing their AD to Azure is because they want to use a single form of identity across Office 365 and on perm infrastructure.

Azure AD Connect gets a log of updates, and sometimes you will get two updates in a single month.


To upgrade Azure AD, Connect, you will need to enter the login details of an Office 365 Global Administrator account.

So, make sure you have the above ready, also during the upgrade process sync between AD and Azure AD is stopped, so make sure you do it during off-peak hours.

The update process will take a few minutes, and when it is done, Azure AD Connect will do a full sync of all objects to Azure AD.
