SCSM Migration

Hello dears,

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 !?

Hi @HebaWagih-9048 ,

How many SCSM Management Servers are you running? Portal Server, SCSM Data Warehouse server?
You are planning a in-place migration?

Based on this details it's easier to talk about a migration strategy.

Hello

We have one management server with management database and self-service portal on the same VM and one data warehouse management server and data warehouse database on the same VM, the two VMs have windows server 2012 as OS version and SQL 2014 as SQL version and our SCSM version is 1807. we can't do in-place upgrade due to the OS & SQL versions

It's not that easy because some of your components or better their versions are outdated

I would try the migration this way (just a draft!):

  • First of all and really important: Have a good backup and restore strategy!

  • Install 2 new servers (will be later the SCSM and SQL servers) with the OS you targeting

  • Install SQL server on both new servers

  • Move the SCSM DBs to the new servers

  • Unregister the SCSM Data Warehouse

  • Inplace Upgrade on the existing SCSM servers to SCSM 2019 (it might be required to update the OS on the servers to meet the requirements)

  • Install a secondary SCSM management server on the new server

  • Promote the new SCSM server to primary management server

  • Install SCSM Data Warehouse Management Server on the new SCSM DWH server

  • Register the new SCSM DWH server

  • Deinstall the "old" SCSM Management Server

  • Deinstall the "old" SCSM DWH Management Server

The list might be not complete. There might be a step missing in the list.

You can test the migration strategy this way:
