Tasks to Perform Before Beginning the VMM Upgrade
Updated: May 13, 2016
Applies To: System Center 2012 R2 Virtual Machine Manager
Before you can install Virtual Machine Manager (VMM) in System Center 2012 R2, you need to uninstall the current version of VMM and prepare the environment by performing the following tasks:
Complete all jobs that are currently running in VMM. You can use the console to view the jobs’ status. All job history is deleted during the upgrade.
Close any connections to the VMM management server, including the VMM console and the VMM command shell.
Close any other programs that are running on the VMM management server.
Ensure that there are no pending restarts on the computers on which the VMM roles are installed. For example, if you have installed a server role by using Server Manager or have applied a security update, you may need to restart the computer. After you have restarted the computer, sign in to the computer with the same user account to finish the installation of the server role or the security update.
If Windows Azure Hyper-V Recovery Manager is implemented in the VMM environment, ensure that version 3.3.140.0 or later of Windows Azure Hyper-V Recovery Manager Provider is installed on the VMM management server. After the upgrade, you will need to re-install the Windows Azure Hyper-V Recovery Manager Provider, to ensure that it works properly.
Perform a full backup of the VMM database. For more information, see Back Up and Restore Virtual Machine Manager. You can also use tools that are provided by SQL Server to back up the VMM database. For more information, see Backing Up and Restoring Databases in SQL Server.
Uninstall the following:
Unless Update Rollup 4 for System Center 2012 SP1 has been applied – Uninstall Update Rollup 3 for System Center 2012 SP1, or any other Update Rollups that were applied that are earlier than Update Rollup 4.

Ensure that the server meets all requirements for VMM in System Center 2012 R2 as described in System Requirements for System Center 2012 R2 and in Preparing your environment for System Center 2012 R2 Virtual Machine Manager.
If needed, upgrade SQL Server to a supported version, as described in SQL Server Requirements for System Center 2012 R2. If the current version is supported in System Center 2012 R2, this upgrade is not required.
Install Windows 8.1 Assessment and Deployment Kit (Windows ADK).
If the current database is configured with AlwaysOn Availability Groups, complete the following tasks:
If the VMM database is included in the availability group, remove it. You can use the Microsoft SQL Management Studio tool to perform this task.
Initiate a failover to the computer that is running SQL Server and on which the VMM database is installed.
You can now upgrade VMM.
