Hi Faisal,
The best guide on the topic comes from Marcel Zehner:
Dealing with multiple Management Servers 3/3: Decommission old Management Servers
Because there isn't much changed in SCSM since then, those steps still apply even to the newest SCSM version.
The summary is:
- Ensure the Management Server isn't also the main workflow server.
- Uninstall the Management Server and the Portal (Uninstall Program from the Control Panel)
- Unregister the DataWarehouse Server
- Uninstall the Data Warehouse Management Server (Uninstall Program from the Control Panel)
- Post-Uninstall Tasks (Remove computer accoutns, SCPs, SPNs, etc.)
- Cleanup
Here also a similar thread:
Decommission SCSM servers
That should do it. Regards,
