Moving from scom 2012 R2 to scom 2019. Should we start with new MPs?

How can we export sealed and unsealed MP in SCOM 2012 R2 then import these to SCOM 2019?

What is the reason that sealed MP is exported as unsealed (XML)? You cannot import it again?

Can unsealed MP (Ops console) on SCOM 2012 be exported and then imported into the SCOM 2019?

    You should download the latest versions of microsoft and third-party MPs.
    Sealed MPs can't be exported as sealed MPs.
    Yes, unsealed MPs can be exported and it should be possible to reimport most (if not all) of them without issue.

    > Should we start with new MPs?

    Moving from SCOM 2012 R2 to SCOM 2019, you may resue SCOM 2012 R2 MPs.
    There are two types of MP, sealed MP and unsealed MP. A sealed management pack is a binary file that cannot be edited. An unsealed management pack is an XML file that can be edited.
    Usually, MS free-MPs and vendor MPs are sealed MP and custom MPs are unsealed. when moving from SCOM 2012 R2 to SCOM 2019, the recommend steps of MP transition as

    1. download more up-to-date MP from MS or vendor
    2. Export custom MP as XML
    3. Import MP into SCOM 2019

    Exporting a management pack allows customizations to a sealed management pack to be saved to a writeable management pack. Because sealed management packs cannot be changed, the modifications made to a management pack are saved to a separate, unsealed management pack file. The unsealed management pack can then be imported into a different management group or the same management group depending on the situation. This unsealed management pack is dependent on the original sealed management pack and can be imported only to management groups that have the original sealed management pack.

    owershell cmdlet to export management pack:
    Export-SCOMManagementPack [-ManagementPack] <ManagementPack[]> -Path <String>
    e.g.
    Get-SCOMManagementPack -Name SNMP | Export-SCOMManagementPack -Path "C:\MPArchive"
