- Mark all the rule groups as disabled and wait one week. The "one week" time period is because a rule group can’t be deleted until MOm has groomed out any live data. If you have a four-day retention period before grooming, you would wait 4 days.
- Delete the rule groups(s).
- Delete the computer group(s).
- You can delete any scripts that were used as part of the management pack – but be careful! Verify that the scripts are not used by any other rules.
Microsoft did have a knowledge base article discussing several methods to uninstalled management packs, but it has been pulled. In case it comes back, the link is http://support.microsoft.com/kb/918278.
Perhaps the easiest way to keep a management pack from functioning is through disabling the computer groups it uses (if they are not used elsewhere) or disabling its rule groups. Making a management pack non-functional is less work and a less risky process than actually deleting it.
