Windows Admin Center requires PowerShell features that are not included by default in Windows Server 2012 and 2012 R2. To manage Windows Server 2012 or 2012 R2 with Windows Admin Center, you will need to install WMF version 5.1 or higher on those servers.
Microsoft hyper-V server 2012 R2 2016
We are building 2016 VMs on 2012 R2 Hyper V host and it's supported by MS. But the hardware doesn't support Windows 2016 on host servers, will this cause any issues with 2016 VMs configured on 2012 R2 HV hosts?
This article explains the new and changed functionality of Hyper-V on Windows Server 2019, Windows Server 2016, and Microsoft Hyper-V Server 2016. To use new features on virtual machines created with Windows Server 2012 R2 and moved or imported to a server that runs Hyper-V on Windows Server 2019 or Windows Server 2016, you'll need to manually upgrade the virtual machine configuration version. For instructions, see Upgrade virtual machine version.
Manage earlier versions - With Hyper-V Manager in Windows Server 2019, Windows Server 2016, and Windows 10, you can manage computers running Hyper-V on Windows Server 2012, Windows 8, Windows Server 2012 R2 and Windows 8.1.
Starting with version 8, generation 2 virtual machines can use significantly more memory and virtual processors. Hosts also can be configured with significantly more memory and virtual processors than were previously supported. These changes support new scenarios such as running e-commerce large in-memory databases for online transaction processing (OLTP) and data warehousing (DW). The Windows Server blog recently published the performance results of a virtual machine with 5.5 terabytes of memory and 128 virtual processors running 4 TB in-memory database. Performance was greater than 95% of the performance of a physical server. For details, see Windows Server 2016 Hyper-V large-scale VM performance for in-memory transaction processing. For details about virtual machine versions, see Upgrade virtual machine version in Hyper-V on Windows 10 or Windows Server 2016. For the full list of supported maximum configurations, see Plan for Hyper-V scalability in Windows Server 2016.
You can now add a node running Windows Server 2019 or Windows Server 2016 to a Hyper-V Cluster with nodes running Windows Server 2012 R2. This allows you to upgrade the cluster without downtime. The cluster runs at a Windows Server 2012 R2 feature level until you upgrade all nodes in the cluster and update the cluster functional level with the Windows PowerShell cmdlet, Update-ClusterFunctionalLevel.
The version represents the compatibility of the virtual machine's configuration, saved state, and snapshot files with the version of Hyper-V. Virtual machines with version 5 are compatible with Windows Server 2012 R2 and can run on both Windows Server 2012 R2 and Windows Server 2016. Virtual machines with versions introduced in Windows Server 2016 and Windows Server 2019 won't run in Hyper-V on Windows Server 2012 R2.
If you move or import a virtual machine to a server that runs Hyper-V on Windows Server 2016 or Windows Server 2019 from Windows Server 2012 R2, the virtual machine's configuration isn't automatically updated. This means you can move the virtual machine back to a server that runs Windows Server 2012 R2. But, this also means you can't use the new virtual machine features until you manually update the version of the virtual machine configuration.
This article describes an update for the latest integrated components for Windows virtual machines (VMs) that are running on a Windows 10-based or Windows Server 2016-based host, or a Windows Server 2012 R2-based host. This update is available on Windows Server 2012 R2, Windows Server 2012, and Windows Server 2008 R2 Service Pack 1 (SP1)-based Hyper-V guest. Before you install this update, check out the Prerequisites section.
The in-place upgrade works smoothly on Windows Server 2012 R2 HyperV to Server 2016. There cant be any open 'saved' sessions and clean shutdown all VM's is recommended before starting the upgrade process.
When you export a virtual machine, it retains its configuration version. The import process on 2016 does not upgrade version 5.0 virtual machines. They will remain at version 5.0 until you deliberately upgrade them. Therefore, just as with Live Migration and Replica, you can use export/import to move version 5.0 virtual machines between 2012 R2 and 2016.
La activación automática de máquina virtual (AVMA) es una nueva tecnología incluida en Windows Server 2012 R2, que le permite simplificar la activación de máquinas virtuales (VM) que se ejecutan en Hyper-V de un host que ejecuta la Datacenter Edition de Windows Server 2016 o Windows Server 2012 R2. Si utiliza AVMA, las VM que ejecutan los sistemas operativos compatibles se activan con respecto a la licencia del host. Para activar una VM no se necesita tener conexión a Internet, y los datos de uso de las VM se almacenan en el servidor host.Situación: después de instalar Windows Server 2016 Datacenter Edition, deberá implementar la VM Windows Server 2016 (Datacenter, Standard o Essentials)
El host Hyper-V debe estar ejecutando Windows Server 2016 Datacenter o Windows Server 2012 Datacenter R2D y estar activado. AVMA no es compatible en las ediciones fuera de Datacenter.
Las máquinas virtuales deben estar ejecutando las ediciones Datacenter, Standard o Essentials de Windows Server 2016 o Windows Server 2012 R2. Las máquinas virtuales deben tener instalada una clave de cliente AVMA (las claves las proporciona Microsoft y están disponibles en este artículo a continuación)
At first I wanted to join the hyper-v server nodes to the windos server cluster but during a test everything failed to stay online as it should (one of the reason for the upgrade) so I cannot do it from the cluster. I also cannot add the 2016 servers to the 2012 cluster, the validation wizard gives an incompatibility error for the os.
I could now manage the virtual machines of the hyperv servers and found out I can also now do a live migration remotely from the admin-client with no problem. Be it from HYPERV2012R2 to W2016 or W2016 to W2016 if I do it from that admin-client.
EDIT: One of the Hyperv2012r2 servers started giving me "faild at source" errors (while the other server is doing great), the solution to that problem was to open a command prompt on the source server and do "net stop vmms" and "net start vmms".
You can install the SVP software on a Windows Server 2012 R2 (64-bit), Windows Server 2016 (64-bit) or Windows 10 Enterprise (64-bit) operating system running on a Microsoft Hyper-V Server 2012 R2 Virtual Machine (VM).

"Installed these updates tonight, in a two server Exchange 2016 CU22 DAG, running on Server 2012 R2. After a really long reboot, the server came back up with all the ReFS volumes as RAW," explained a Microsoft Exchange administrator on Reddit.
Microsoft Hyper-V, codenamed Viridian,[1] and briefly known before its release as Windows Server Virtualization, is a native hypervisor; it can create virtual machines on x86-64 systems running Windows.[2] Starting with Windows 8, Hyper-V superseded Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks.Hyper-V was first released with Windows Server 2008, and has been available without additional charge since Windows Server 2012 and Windows 8. A standalone Windows Hyper-V Server is free, but has a command-line interface only. The last version of free Hyper-V Server is Hyper-V Server 2019, which is based on Windows Server 2019.
These steps work for Windows Server 2012, 2012 R2, 2016, 2019 and 2022. The only differences between the graphical user interface is the changes in the dialogs visual appearances. The example provided in this section are taken from Windows Server 2016.
Using Windows PowerShell is the preferred method for setting the MPIO Timer values when managing Windows Server 2012, 2012 R2, 2016 or 2019 using Set-MPIOSetting cmdlet which is part of the MPIO module. 2ff7e9595c
