OLD: Dell PowerEdge 2800 windows 2003 R2 (it is not indicated enterprise 64 bit, therefore it is 32 bit) Domain controller/File server
New: PE Server with windows 2012 R2
I am going to migrate windows 2003 R2 Domain controller to Windows 2012 R2 (64 Bit) domain.
The first thing is to prepare the existing domain and solve any issue with DNS and AD but I can not locate the original CD that customer had received, to install MS Support Tolls and be able to run dcdiag.exe or other utility before going further.
I have used several other windows 2003 server CD that it is not the right version. Attached is the windows server OS that I have on old Domain controller. Please advise..
