Upgrade Windows Hyper-V Cluster 2012 R2 to 2016 – Cluster Operating System Rolling Upgrade
Cluster OS Rolling Upgrade is a new feature in Windows Server 2016 Technical Preview that enables an administrator to upgrade the operating system of the cluster nodes from Windows Server 2012 R2 to Windows Server 2016 Technical Preview without stopping the Hyper-V or the Scale-Out File Server workloads. Using this feature, the downtime penalties against Service Level Agreements (SLA) can be avoided.
