I’ve recently updated my Windows Server 2008R2 system to Windows Server 2012. Windows\u00a0Server 2012 was a fresh install using a different domain name on a new system. My intention was to manually migrated all data from the existing 2008R2 server into the new domain, this included Hyper-V VMs, DHCP and GPOs. There is the option of using ADMT however I required a clean install.<\/p>\n
These are the steps I took in order to migrate GPOs from the source server to the destination server with a different domain name.<\/p>\n
(Although this was completed from a 2008R2 to 2012 server, the first set of screen shots where created on the new 2012 server for this guide)<\/p>\n
Source WS2008R2:<\/strong> Backup the existing GPOs from the GPMC, you need to ensure that the “Group Policy Objects” container is selected for the “Backup Up All<\/em>” option to be available. <\/strong><\/p>\n ngg_shortcode_0_placeholder<\/p>\n Source WS2008R2: <\/strong>Select backup location. This will backup all<\/span> GPOs on the server. This is basically creating a copy of the SYSVOL GPOs files\/folders “%systemroot%\\SYSVOL\\domain\\Policies” The backup location DIR can be checked to confirm these are available. i.e. S:\\Backup, this should match %systemroot%\\SYSVOL\\domain\\Policies<\/strong> Destination WS2012: <\/strong>Depending on the GPOs being migrated some of these may have references to local domain varibles such as “domain.com” or SIDS. Before the GPOs can be imported, these\u00a0varibles must be remapped\u00a0to work correct in the new domain. To remap these the Migration editor can be used.<\/p>\n Select “Open Migration Table Editor”<\/strong> Select “Tools -> Populate from Backup”<\/strong> “Browse” to the GPO backup location\u00a0(i.e. S:\\Backup) highlight GPOs\u00a0and select\u00a0“OK”<\/strong> Review\u00a0any objects that reference\u00a0the source domain,\u00a0right click the field which requires updating, select “browse” and select\u00a0a\u00a0new target which exists in the\u00a0destination domain (i.e. groups, users, computers, SIDS etc)<\/strong> After reviewing\/updating objects, the list needs to be saved into a .migtable file
