Upgrading to System Centre 2012 – Operations Manager

Direct upgrade to SCOM 2012 is supported only from SCOM 2007 R2 with CU4. All SCOM 2007 R2 management servers to be upgraded must be 64-bit on x64 hardware and be running Windows Server 2008 R2 SP1.

Order of Upgrade:

The general order of upgrading is secondary management servers, gateways and agents first, then the Root Management Server (RMS). The upgrade will be blocked if any management servers or gateways are still SCOM 2007 R2. It will be highlighted during the RMS upgrade if any agents are still SCOM 2007 R2, but it won’t block the upgrade. Those agents just won’t be able to report until they’ve been upgraded to SCOM 2012 agents.

In a smaller environment with an all-in-one SCOM 2007 R2 server, an in place upgrade can be done if the server meets the hardware and software requirements. All the agents must be upgraded to SCOM 2012 before upgrade so that they will report to SCOM 2012 after successful upgrade.

Microsoft TechNet Library provides different flow diagrams to help with migration planning. It also provides links to checklists with step-by-step instructions.

Upgrade pre-requisites:

  1. Check if all the requirements listed in the TechNet site are met http://technet.microsoft.com/nl-nl/library/hh205990%28en-us%29.aspx
  2. Minimum cumulative update version installed must be CU4, confirm the version number (6.1.7221.61) from SCOM console about tab under help.

Co-existence:

You might have a blend of SCOM 2007 R2 and SCOM 2012 management groups and servers in your environment for a while, so it’s good to know SCOM 2012 agents will communicate with SCOM 2007 R2 servers. It won’t work the other way around, however, so it’s important to upgrade your older agents as soon as possible.

Management Packs:

The Management Pack schema remains unchanged so all MPs that work with SCOM 2007 R2 should work in SCOM 2012. Some exceptions include some third-party MPs requiring new modules on the agent, new MP templates or new view types due to API changes. Network monitoring MPs leveraging Simple Network Management Protocol (SNMP) will continue to work, but might require updating to integrate with the new network monitoring framework.
