Remove SCOM Management packs with PowerShell

After importing a newer version of SQL Management pack, in our case (7.0.15.0). The older SQL Management packs are no longer needed, because the new one is version-agnostic.

As described in the release notes:
This management pack is version-agnostic, which means that you need only it to monitor SQL Server from 2012 to 2017 and higher. The previous management packs for SQL Server 20082012, 2014, and 2016 have reached the end of support. After importing, this management pack behaves differently depending on whether there are already the previous management packs installed or not. If those are not installed, the management pack will discover and monitor SQL Server 2012, 2014, 2016, 2017 and higher right out of the box, as the previous management packs do that. In the case when there is one or several of the previous management pack for SQL Server 2012, 2014, and 2016, the version-agnostic management pack will disable the discovery and monitoring for those versions of SQL Server that are already monitored by the previous management packs. It is to avoid double monitoring.

Now, it’s time to delete all older SQL Management packs.
Open your Operations Manager PowerShell window. If you cannot find the shortcut on your management server, you can also do a “import-module operationsmanager”
