In the instructions for moving Windows SBS 2003 settings and data for Windows Server 2012 Essentials migration, we are instructed to remove legacy Active Directory Group Policy Objects, and to remove WMI filters for PreSP2 and PostSP2. I did not do not so prior to joining the Server 2012 to the domain and replicating Active Directory between the SBS 2003 Server and Server 2012. Are these GPO's colliding with GPO's configured on the Server 2012? Should I go ahead and now remove legacy GPO and WMI filters from the Server 2012?
I am actually running Windows Server 2012 Standard.
