hi,
our existing scom 2016 environment is distributed and has all of the databases located on a remote sql server (sql 2016 sp2). we'd like to upgrade scom to 2019, but we don't want to continue running the scom servers on the old server os (2012R2). i understand i can upgrade the 2012 R2 windows os in place, but I was wondering if it's possible to just deploy a new server with server 2019, install scom 2019 and join it to the management group and then remove the scom 2016 servers on the 2012 R2 os's from the management group? i'm having trouble searching the internet for that scenario.
thanks!
Hi @not my name ,
SCOM 2016 can coexist with SCOM 2019 (see Supported coexistence), so it is possible to install a SCOM 2019 environment on the side, then you can make your SCOM 2016 agents report to your SCOM 2019 management group, and slowly perform a side-by-side migration.

ok. i think i understand. with the side-by-side migration i'll have to create new databases correct? meaning i lose whatever's in the old databases. also, am i making a new management group as well?
With side-by-side migration you install a new database & management group on the side yes.
i don't love the idea of new databases. we don't want to lose historical data. what about this as a scenario:
that way we don't have to create new databases or management groups or do any other side by side migration. like an in place upgrade with extra steps.
That will work, note however that SCOM 2016 is not supported on Windows Server 2019, so if you want to run a supported environment run them on Windows Server 2016.
Once you upgrade to SCOM 2019, you can install new Windows Server 2019 SCOM management servers or in-place upgrade your Windows Server 2016 ones.

If you want to stick to an in-place upgrade, what you could do is :
@not my name , Agree with Leon, For SCOM 2019, we can install it on Windows server 2019. And SCOM 2016 with the latest update rollup can coexist with SCOM 2019. Here is a link for the reference:
https://learn.microsoft.com/en-us/system-center/scom/system-requirements?view=sc-om-2019#software-requirements-for-operations-manager-components
Before the side-by-side migration, we need to verify something like if the SQL version and service pack levels are supported for both SCOM 2016 and SCOM 2019, if all AGENT managed Operating Systems are supported for SCOM 2019. if all MANAGEMENT PACKS in use are supported for SCOM 2019. here a blog from Kevin for the reference:
https://kevinholman.com/2021/01/13/upgrade-from-scom-2016-to-scom-2019-checklist/
Note: Non-Microsoft link, just for the reference.
We can plan a side by side migration with the steps which Leon mentioned:
