Upgrading Windows 7 Pro vs Enterprise

    Question

  • I've a Windows 7 Professional and I want to upgrade to Enterpside edition.
    When I try to do this, I receive this error message:
    "Windows 7 Professional cannot be upgraded to Windows 7 Enterprise. You can choose to install a new copy of Windows 7 Enterprise instead, but this is different from an upgrade, and does not keep your files, settings, and programs. You’ll need to reinstall any programs using the original installation discs or files. To save your files before installing Windows, back them up to an external location such as a CD, DVD, or external hard drive. To install a new copy of Windows 7 Enterprise, click the Back button in the upper left-hand corner, and select “Custom (advanced)”. "

    Can anyone help me?

  • Hi Matteo,

    Upgrade from Windows Vista to Windows 7 is not called "Windows Anytime Upgrade". It is an inplace upgrade. See this table:

     

    From Windows Vista (SP1, SP2)

    Upgrade to Windows 7

    Business

    Professional, Enterprise, Ultimate

    Enterprise

    Enterprise

    Home Basic

    Home Basic, Home Premium, Ultimate

    Home Premium

    Home Premium, Ultimate

    Ultimate

    Ultimate


    We cannot use inplace upgrade to upgrade Windows 7. It can only help repair the system:
     

    From Windows 7

    Repair-In-Place Upgrade to Windows 7

    Enterprise

    Enterprise

    Home Basic

    Home Basic

    Home Premium

    Home Premium

    Professional

    Professional

    Starter (x86 only)

    Starter (x86)

    Ultimate

    Ultimate

     

    So in order to help upgrade to Enterprise, we will need to do a clean install. To transfer data we can use the Windows Easy Transfer.

  • As it mentioned, Windows Anytime Upgrade do not support upgrade Wnidows 7 Professional to Windows 7 Enterprise. So we will have to do a clean install to build a new system.

    If we would like to transfer files, use the Windows Easy Transfer.

  • This are only for customer. We are a Enterprise and we have downloaded Win7 distribution from licensing site of Microsoft where I find Win7 Ent Upg.
    I've made the upgrade with Vista and works fine, but not with Win7.
    Ultimate version of Win7 isn't for Enterprise contract.

    Kind regards.
