SCSM 2016 - Upgrade
Upgrading to System Center Service Manager 2016 can be a straight forward process, but requires
careful the planning and testing to have a successful migration. This blog post hopefully will help by providing a high-level summary of the SCSM Planning and Deployment notes from Microsoft.
The SCSM 2016 upgrade is essentially an in-place upgrade and looks very much like an install of SCSM 2012. If you have meet all the compatibility requirements and prerequisites for SCSM 2016 it should be a smooth upgrade. But there are some gotchas in the compatibility guides and it is an all or nothing upgrade.
You cannot mix and match SCSM and SCSM 2016 at any level – Server, Client Console or Self-Service Portal (SSP). Everything has to be SCSM 2016 or everything SCSM 2012. As you are upgrading, components will be at different versions, but the environment is not functional at this point. Plan for a substantial outage to the SCSM environment while you do the upgrade.
Testing of third party and custom development is also extremely important. Changes with Microsoft .NET Framework 4.5.1 mean that SCSM third party tools will break in SCSM 2016 and will need to be upgraded\reinstalled with versions compatible with SCSM 2016.
The changes with .NET Framework 4.5.1 will potentially apply to any other custom development, usually if it involved writing code it will need to upgraded\recompiled for .NET Framework 4.5.1, but it will depend on what was done. Extending classes and forms with the Authoring tool will generally be compatible, but always test before starting a production migration.
System Center Suite Upgrade Order
The upgrade order for System Center components is important and is the same as System Center 2012. Refer to Upgrading System Center 2012 R2 - Service Manager to System Center 2016 and Upgrade Sequencing for System Center 2012 SP1
Upgrade System Center components in this order:
Data Protection Manager
Virtual Machine Manager
Note: You can only upgrade to SCSM 2016 from SCSM 2012 R2 with Update Rollup 9 or later installed.
High Level Steps for upgrading SCSM 2016
This is a high level guide of the overall process, rather than a guide of installing SCSM 2016. Refer to our blog SCSM 2016 - Upgrade Screen Shots for the detailed steps involved.
Step 1: Meet Compatibility Requirements
All SCSM servers need to be Windows 2012 R2 or higher.
This might require adding new management servers on Windows 2012 R2 and then retiring any Windows 2008 / 2008 R2 management servers.
Look at the disaster recovery steps on how to move the SCSM workflow and Data Warehouse servers:
Upgrade or move to SQL 2012 SP2
Confirm third party vendor support for SCSM 2016
Confirm any custom development code, workflows or management packs is compatible with SCSM 2016
Confirm the hardware requirements Minimum Hardware Recommendations for System Center 2016. There are no surprises here and you should be fine.
SCSM 2016 server is only supported on Windows 2012 R2 and above.
For the databases, only SQL Server 2012 SP2 and above is supported.
Microsoft PowerShell 4 and above is supported with SCSM 2016.
Probably at least one of these will have an impact and if you are unlucky all of them. Getting the existing SCSM 2012 environment compatible with SCSM 2016 is the first major step. This may take some time and involve other teams (client windows version or server versions) before you will be ready to migrate to SCSM 2016.
Third Party Tools Most, if not all of them will need to be upgraded or re-installed for SCSM 2016. The implementation of Microsoft Framework .NET 4.5.1 made some changes to where things were stored and any plug-ins will need to be updated to reflect those changes.
The good news is that most third-party vendors have released SCSM 2016 versions. But before migrating, check what you are using and confirm you have a SCSM 2016 version. Follow the vendor instructions for upgrading to SCSM 2016. Custom Development If you have customized to the point of writing code you will probably need to update the code for SCSM 2016. Refer to SCSM 2016 – Upgrade steps for custom development and SCSM 2016 - Steps for Upgrading Custom Development
If you have extended classes and forms, these should not be affected. But test anyway. It is generally only when you have compiled code against .NETor written specific workflows that you will need to rewrite\re-compile the code.
Step 2: Read the Release Notes
