Posted on by

Windows 2012 logoIn this blog post , I am going to list the steps involved in transition from a Windows 2003 R2 Small Business Server Domain Controller to a Standard Windows 2012 Domain Controller.

In my situation we have a linux server (using ext3 file system), with several SMB shared folder used by all the MAC/Linux/Windows workstation:  a very cheap backup system consist in a USB disk connected directly to the server, and a daily backup process that copy all the files from shared folders to this disk.
