Cluster Operating System Rolling Upgrade in Windows Server Technical Preview #Winserv #Hyperv

Cluster OS Rolling Upgrade

Cluster Operating System (OS) Rolling Upgrade is a new feature in Windows Server Technical Preview that enables an administrator to upgrade the operating system of the cluster nodes from Windows Server 2012 R2 to Windows Server 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.

Cluster OS Rolling Upgrade provides the following benefits:

  • Hyper-V virtual machine and Scale-out File Server workloads can be upgraded from Windows Server 2012 R2 to Windows Server Technical Preview without downtime. Other cluster workloads will be unavailable during the time it takes to failover to Windows Server Technical Preview.
  • It does not require any additional hardware.
  • The cluster does not need to be stopped or restarted.
  • A new cluster is not required. In addition, existing cluster objects stored in Active Directory are used.
  • The upgrade process is reversible until the customer crosses the “point-of-no-return”, when all cluster nodes are running Windows Server Technical Preview, and when the Update-ClusterFunctionalLevel PowerShell cmdlet is run.
  • The cluster can support patching and maintenance operations while running in the mixed-OS mode.
  • It supports automation via PowerShell and WMI.
  • The ClusterFunctionalLevel property indicates the state of the cluster on Windows Server Technical Preview cluster nodes.

This guide describes the various stages of the Cluster OS Rolling Upgrade process, installation steps, feature limitations and frequently asked questions (FAQs), and is applicable to the following Cluster OS Rolling Upgrade scenarios in Windows Server Technical Preview:

  • Hyper-V clusters
  • Scale-Out File Server clusters

The following scenarios are not supported in Windows Server Technical Preview:

  • Cluster OS Rolling Upgrade of a cluster using storage with the Data Deduplication feature
  • Cluster OS Rolling Upgrade of virtual machines with Data Protection Manager (DPM) backups
  • Cluster OS Rolling Upgrade of guest clusters using virtual hard disk (.vhdx file) as shared storage
