Organizations that have previously downloaded and deployed the free Microsoft iSCSI Software Target 3.3 for Windows Server 2008 R2 need to be aware that if you need to manage a heterogeneous environment that includes target servers and initiators for Windows Server 2012 and Windows Server 2008 R2, you might need to use separate management tools for doing this. For example, the iSCSI Target MMC snap-in for Windows Server 2008 R2 cannot be used to manage target servers running Windows Server 2012. Furthermore, Windows PowerShell commands and Windows Management Instrumentation (WMI) scripts used for managing the Microsoft iSCSI Software Target 3.3 might need to be modified if you want to use these commands and scripts to manage the iSCSI Target Server capabilities in Windows Server 2012.
The above tip was excerpted from Mitch Tulloch's book Training Guide: Installing and Configuring Windows Server 2012 from Microsoft Press.
