Thanks in advance. I Just successfully migrated windows 2008 DC to windows 2012 DC, After migration I checked all OUs and objects inside OUs are successfully migrated to 2012. I also checked users are successfully log in to windows 2012 domain. The problem is when I check the computer name in windows 2012 DC and still showing the old computer name. Why so. If I want to change it, giving warning ... Please suggest..
The name remaining the same is normal.
