Considering how many people have downloaded my guide on how to build a Hyper-V cluster using the Microsoft iSCSI v3.3 target, I thought you might want to know about this new KB article from Microsoft: “Migrating iSCSI Target 3.3 settings before upgrading Windows Server 2008 R2 to Windows Server 2012”.
Consider the following scenario:
- You have a computer that is running Windows Server 2008 R2 or Windows Server 2008 R2 Service Pack 1 (SP1)
- You have configured Microsoft iSCSI Software Target 3.3
- You start the upgrade of the operating system to Windows Server 2012.
- When you proceed through the Upgrade wizard, the compatibility report shows the following message: Installing Windows will affect the following features:
Setup has detected that Microsoft iSCSI Software Target or Microsoft iSCSI VDS/VSS providers are installed on this computer. They will no longer function after the upgrade and configuration settings will be lost You must follow the instructions at <Link> prior to the upgrade to ensure they can continue to work after successful upgrade.
In this scenario, setup gives you a warning that, Microsoft iSCSI Software Target 3.3 or Microsoft iSCSI VDS/VSS providers may not be functional after the upgrade. It is best to uninstall the feature, then enable the feature after upgrade the server to Server 2012.
Cause: In Windows Server 2012, the Microsoft iSCSI Software Target and Microsoft iSCSI VDS/VSS providers are available as a built-in sub feature of the File and Storage Services Role.
