Note that this is still beta at present.
There are two ways to upgrade:
use the Easy Transfer Wizard and then a clean install and let the
wizard recreate your files and settings. You will need to reinstall all
your programs.

is for Vista but there will be an equivalent for Windows 7;
or just back up your files and settings and do a clean install then
recover your files to the new installation.
You can buy an upgrade edition of Windows 7 or the 64-bit OEM version.
The upgrade edition will have both 32 and 64 bit disks. The OEM version
will be 64-bit only.
