Hi, Can somebody detail or provide links on how to migrate Active Directory from an MS Windows Server 2008 server to a separate MS WIndows Server 2012 server - to include the Global Catalog, FSMO and other roles, and also DNS and WINS (which are running on the current WIndows Server 2008 AD server but need to be moved or replicated on the new MS Win2K12 server) ?  The Win2K8 server is a physical server while the new Win2K12 server will be virtualized with VMware (so both can and will be up and running simultaneously for a while). TIA,

i would substitute this article for step 4; easier from the command line and the article above only covers 3 of the 5 roles

Using Ntdsutil.exe to transfer or seize FSMO roles to a domain controller

DNS gets replicated automatically once it's promoted

this would help with making the 2012 server a global catalog (if it already isn't)

Add or Remove the Global Catalog

do you have a legacy requirement to keep wins?  if not, you should move off it since it's an old technology and really not needed anymore unless there is a specific reason.  modern operating systems use DNS isntead of wins

also, the article above mentions 2008 R2 though you state 2008....please clarify which version as it could make a difference in your forest/domain schema update

This is perfect, thanks all !  There are currently some legacy apps that still need WINS, but the process to get off of WINS will be accelerated. I believe the Win2K8 DC is in fact the first version of Win2K8 and not the R2 version (but I would have to confirm).    If is is in fact the first version are there any extra steps we should take for the forest/domain schema update ?
