Hi, I am doing a parallel migration of SCOM. I installed SCOM 2012, I am pushing the SCOM 2012 Agent. I want to clean the old management groups.. but i do not find a possible solution using command line http://technet.microsoft.com/en-us/library/hh212772.aspx For a big number of servers to go and remove from "Operation Manager Agent Properties" .... is complicated. I am thinking of deleting the registry key folders from the old MG.

Hello Adrian, You can use the below method either (Manual, Using SCCM or PSExec.exe) This post explains what the command line switches need to be in order to remove old management group configuration. http://blogs.technet.com/b/jonathanalmquist/archive/2009/12/30/agents-remove-configured-management-group-or-uninstall-agent-using-command-line.aspx Remove a specific MG configuration from the agent MsiExec.exe /i \\path\MOMAgent.msi /norestart /qn /l*v %temp%\RemoveMG.log MANAGEMENT_GROUP=<OldManagementGroup> MANAGEMENT_GROUP_OPERATION=RemoveConfigGroup REINSTALL=ALL This thread is discussing similar issue, please check it: http://social.technet.microsoft.com/Forums/en-US/operationsmanagerdeployment/thread/336729ce-f457-4736-8e38-1865a2b0b88e/ Regards, Mazen Ahmed

Did you try that fro SCOM 2012 Agent? at me did not worked :) This thing MANAGEMENT_GROUP_OPERATION=RemoveConfigGroup does not exist any more!

Hi Adrian, Check this command MsiExec.exe /i \\path\Directory\MOMAgent.msi /norestart /qn /l*v %temp%\MOMRemove.log MANAGEMENT_GROUP=<OldManagementGroup> MANAGEMENT_GROUP_OPERATION=RemoveConfigGroup MANAGEMENT_SERVER_DNS=<OldManagementServerName> REINSTALL=ALL from the MS site, http://technet.microsoft.com/en-us/library/ee424297.aspx The command given by Mazen works fine on a 2007 r2. This commad has an additional switch for MANAGEMENT_SERVER_DNS Let us know if this works. Regards, Dhanraj

Hi, My SCOM curently is SCOM 2012, so I need to remove the management group with a comand line that will work with SCOM 2012 Agent (not with SCOM 2007 R2 agent)

Hi Adrian, Due to your question I have made a blog post about how to remove a manmagement group from an existing multihomed SCOM 2012 agent and added how to do the same for adding a management group entry to an agent like that.
