During migration and upgrade process of our SCVMM server from 2012R2 to 2016 version we ended up with having our old and decommissioned VMM server.
We wanted to upgrade Servers to Windows server 2016 and to SQL 2016 version.
As part of this migration and upgrade, we ended up migrating and restoring our VMM DB to new server, and deploying new VMM.
As result we had fully functional SCVMM 2016 server. One thing was bugging me is that there was information in SCVMM that we have two SCVMM servers as part of infrastructure. One SCVMM server was running and responding state and second was unresponsive with no option to remove it using SCVMM console.
