Hi,
If you mean upgrading only the Excel Starter 2010 to a full version, you can purchase a Stand-alone version of Excel.
For using the Office 2003 products on new laptop, you’d better to contact Microsoft Customer Service to confirm it.
Usually, we cannot transfer the Office 2003 programs from one computer to another because the product key may be used for 1 user 1 PC.
Sincerely
Rex Zhang
