Remove Management Group SCOM 2012
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 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. 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: Regards, Mazen Ahmed

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, 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. Manipulating SCOM 2012 agent multihoming options by script You can downlaod the scripts from the Technet Gallery as referenced from the blog post.
