Install Sunset on the new machine. Only bring your *.mny and recent *.mbf files to the new machine. Be sure that your Money (*.mny) and backup (*.mbf) files are copied to a spot that you will have full privileges to, such as Documents.
If they are in a place like ProgramFiles, Windows 7 will create an impermanent copy of the file for the user to use, unless the user
explicitly right-clicks at launch and choose RunAsAdministrator that time.
After you open your Money file on your new setup, whatever version, change the location to which Money backs up to a location that
exists on the new computer -- typically your Documents folder or a sub-folder in Documents.
Look to PocketSense to download OFX statements from your broker and credit card.
While you are thinking about it, review your backup policy. Include the periodic use of other media, and even consider off-site backup.
