Migrating from Server 2012 to 2016#
Existing Microsoft Hyper-V customers on Windows Server 2012 R2(v1) are joined to self hosted domains within their Hyper-V clusters. New customers on Windows Server 2016(v2) are on a centrally controlled domain managed by Rackspace. Customers can migrate all of their hypervisors from Windows Server 2012 R2(v1) to Windows Server 2016(v2) through certificate based replication.
At this time, live migration and storage migration across domains has several restrictions. Speak to your Microsoft Hyper-V Rackspace support team for more information.
Certificate based replication is utilized to move VM tenant workloads from the customers existing 2012 environment to the new 2016 environment.
If you want to migrate from 2012 to 2016, submit a ticket with your account or service delivery manager. The Rackspace Microsoft Hyper-V Support team builds out your new 2016 environment, and replicates your pre-existing environment.
There is no downtime during this process until VMs require updating. In order to process the upgrade of the virtual machine, the VM(s) have to be shutdown before backups in the 2016 environment are successful.
