Tasks to Perform Before Beginning the Upgrade to VMM in System Center 2012 SP1
Applies To: System Center 2012 SP1 - Virtual Machine Manager
Before you can install Virtual Machine Manager (VMM) in System Center 2012 Service Pack 1 (SP1), you need to uninstall the current VMM and to prepare the environment by performing the following tasks:
Complete all jobs running in the current VMM installation; you can use the console to view 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 open programs 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, log on to the computer with the same user account to finish the installation of the server role or the security update.
Perform a full backup of the VMM database. For information about backing up the VMM database, see Back Up and Restore Virtual Machine Manager. You can also use tools provided by Microsoft SQL Server to back up the VMM database. For more information, see Backing Up and Restoring Databases in SQL Server.
