Identifying and removing components of an old SCOM 2016 installation

Question

I need to remove any remnants of an old SCOM 2016 installation to ensure that servers stop referring to the old SCOM server that no longer exists. How can I identify and remove components or configurations related to the old installation?

Are there specific files, registry entries or services that I should target for removal?

I appreciate any insights or recommendations.

Hi,

To remove remnants of an old SCOM 2016 installation, you can follow these steps:

1. Uninstall SCOM Components:

• Use the Control Panel to uninstall any remaining SCOM components like the Management Server, Console, and Web Console.

2. Remove Registry Entries:

• Open the Registry Editor (regedit) and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0. Delete this key if it exists.
• Check for any other SCOM-related keys under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.

3. Inspect Resource Pools:

• Make sure the old management server is removed from any resource pools with manual membership and add the new management servers to those pools.

These steps should help you thoroughly clean up any remnants of the old SCOM 2016 installation. If you encounter any specific issues, feel free to ask for more detailed guidance!
