Warning: Older Operating System

The operating system version on the new replacement computer is older than the operating system version on the old domain controller. Or the migration target is not supported by U-Move.

To upgrade Active Directory to a new replacement computer, the new computer needs to have the same or newer version of Windows Server installed on it.

Some upgrade combinations are not supported. (For example, downgrading from from Windows Server down to Small Business Server is not supported.) See the list of suported OS upgrade combinations.
