There are a few things to know when migrating from Windows XP to Windows 7. When migrating from Windows Xp to Windows 7 you will have no "in place upgrade" option. You will however have the option to select "custom" install when prompted. The Windows 7 install process will then copy all of your data in "My Documents" over to a Windows.old folder within Windows 7 itself. All applications and documents stored in other locations will have to be reinstalled / transfered manually.
