USMT 4 - 64 bit to 32 bit RRS feed

  • Question

  • I'm starting a PoC at my company for Windows 7.  I've configured a "one click" upgrade process that users will execute when they want to launch their XP to Win 7 upgrade.   In 99% of the cases our devices are running 32 bit images, and will be upgraded to a 32 bit build of Windows 7.

     In one case I have someone who went ahead and installed Win7 x64 on their own, and they are targeted in the PoC.  (Management wants to standardize everything and im all for it).


    My question is, does anyone have any detail as what to expect with running a full USMT backup on a 64 bit device, and restoring on a 32?  I may advise running a newcomputer build in this case since the scenario is pretty much out of scope, but I wanted to throw the question out there just in case others have had experience of it working well.  I can't imagine many scenarios where this has been tested however.

  • Not compatible.

    USMT migrates files and settings between Microsoft Windows versions 2000, XP, Vista and Windows 7, and is useful in migrating user settings and files during OS upgrades. 32-bit to 64-bit migrations are supported, but 64-bit to 32-bit are not.
