This post demonstrates how the Sample Upgrade Helper MP for Operations Manager 2012 SP1 –> 2012 R2, was used when upgrading an Operations Manager 2012 SP1 Distributed Management Group to 2012 R2 in a lab environment (the sample MP can be downloaded from the TechNet Gallery).

Scenario 1:
In this scenario, the Management Server hosting the RMS emulator role was used as the starting point of the upgrade. However, starting the upgrade from the RMS Emulator Role is OPTIONAL. Upgrade can start from any management server in the management group (Demonstrated in Scenario 2).

The management servers run on Windows Server 2008 R2 Enterprise SP1 and the SQL Server version is SQL Server Enterprise Edition (64bit) 2008 R2 SP2 (10.50.4000.0). All are virtual machines running on a Hyper-V host.

Important Note:
When upgrading multiple management servers in a distributed management group, only start upgrade of additional management servers until AFTER SETUP ON THE FIRST MANAGEMENT SERVER COMPLETES. Failing to do so can result in database issues.

Please read the Important Notes specified in the Instance Details widget if any.


The upgrade wizard page listed the following pre-existing features to be upgraded, when the System Center 2012 R2 Operations Manager installation media was run on the Management Server that is hosting the RMS emulator role:

As the Operations Console was available on this Management Server, the Microsoft Report Viewer Redistribution Package and the Microsoft System CLR Type for Microsoft  SQL Server 2012 were required (as specified in TechNet http://technet.microsoft.com/en-us/library/dn249696.aspx). Refer to OpsMgr: SUHMP2012R2 – Upgrading a Single Server Management Group from 2012 SP1 to 2012 R2 for further details.

When all prerequisites were met, upgrade was able to proceed with the default settings accepted for all other pages.

Upgrade of the RMS Emulator and databases completed successfully as shown on the following Setup Complete page (the Retail license was used):

The new upgrade state of the distributed management group shown on the Sample Operations Manager R2 Upgrade MP Dashboard was as follows:
- Notice that the Component Version property of the RMS Emulator has a value of the latest product version number, and that the Overall upgrade state of the management group and the additional management servers still in Warning state at this stage.

Next, running the upgrade wizard on the additional Management Server listed the following pre-existing features to be upgraded,
- The Operations Console, Web Console and Reporting Server role were NOT installed on this management server. 
- The Operational Database and the DW database were not listed as they were already upgraded earlier on from the RMS Emulator.

  • The discoveries and monitors are configured to run at an agressive sample frequency to force faster detection rates and property value updates (30 seconds for the monitors and 300 seconds for discoveries). Use an override to modify the sample frequency value for the monitors and discoveries if required.
