Migrating Highly Available VM Workloads to Windows Server 2012 R2 | Windows Server 2008 R2 Hyper-V Migration to Windows Server 2012 R2
In this blog post we will be discussing the steps involved in migrating the existing Highly Available Windows Server 2008 R2 / 2012 RTM (Clustered) VMs workloads to Windows Server 2012 R2 with the Cluster Migration Wizard. Windows Server 2012 R2 is out now, which is successor of Windows Server Hyper-V and latest version of Hyper-V available in the market. It has tremendous new feature and many enhancement for existing feature carried forwarded from its previous version. I would strongly recommend everyone to put Windows Server 2012 R2 as their production hypervisor for server consolidation and virtualization needs.
This article details the step by step procedure for this migration, which are outlined as following:
- Phase 1 – Building the new Windows Server 2012 R2 Failover Cluster
- Phase 2 – Migrate the VM resources from source cluster (Windows 2008 R2) to target cluster (Windows Server 2012 R2 Cluster) using Cluster Migration Wizard.
- Phase 3 – During a scheduled maintenance window,
- The source VMs should be shut down and turned off.
- The source cluster CSV volumes that have been migrated should be off-lined.
- The storage that is common to both clusters (LUNS) should be masked (hidden) from the source cluster
- The storage that is common to both clusters (LUNS) should be presented to the new cluster.
- The CSV volumes on the target cluster should be on-lined.
- The VMs on the target cluster should be on-lined.
