We are currently planning to upgrade to SCSM 2019 from SCSM 2016. We would like to use all new servers with new names in the new environment but still want to retain the old data (using a BD backup). I have found a good documentation to move SCSM database to a new server https://docs.microsoft.com/en-us/system-center/scsm/move-databases?view=sc-sm-2019 , after doing that and start installing SCSM and use an existing database the installation fails. I think it fails because this article isn't enough we still need to change all management server entries in SCSM DB, but I don't know which entries should we change also, could anyone help me !?
