You don't mention what data you wish to move. If it's contacts & so on, then I find that the Sync section of the Nokia package works well with Outlook - in fact it was a life-saver when my contacts file got corrupted some months ago: nearly everything could be retrieved from the phone.
If it's pics, music, ringtones and so on, then the File Manager section of PC Suite should transfer to a temp folder on your PC and back again onto the new phone.
... but perhaps you are trying to do summat much more esoteric than that?
