Good morning, I have an HP DL580 G5. I am attempting to upgrade from Windows Server 2008 Standard (Full Installation) (x64) to Windows Server 2008 Enterprise (Full Installation) (x64). When I run the setup.exe from the DVD inside of my current installation, the "Upgrade" option is disabled (greyed out.). According to the link below, this seems to be a supported upgrade path. http://technet.microsoft.com/en-us/library/cc755199%28WS.10%29.aspx#BKMK_Supported The only difference I see is that I've installed SP2. Would that make this upgrade unsupported? Why is my option to upgrade disabled? Current build: Version 6.0 (Build 6002 : Service Pack 2) Install Media: KRMS_XVOL_EN_DVD Thanks for any help.

Yes you can upgrade from windows 2008 Standard to windows 2008 Enterprise. To upgrade, boot on the DVD. Input a Windows Server 2008 Enterprise Key or choose Windows Server 2008 Enterprise and then you can perform an upgrade installation. SP2 may be the cause of the problem. Try to uninstall it and check if this solve your problem or not (Service packs may cause such problems like in this example ).
