This will require you to have a folder called "C:\mp" to store the exported management packs so make sure you create the folder first.
For SCOM 2007:
$mps = Get-ManagementPack | where {$_.sealed –eq $true}
foreach($mp in $mps)
{export-managementpack -ManagementPack $mp -Path "C:\mp"}
For SCOM 2012:
$mps = Get-SCOMManagementPack | where {$_.sealed –eq $true}
foreach($mp in $mps)
{Export-SCOManagementPack -ManagementPack $mp -Path "C:\mp"}
Hope this helps.
