Change NIS2009 Product Key

Hi

Sorry if this solution is listed elsewhere...I checked around and could not find an answer.

 

I purchased NIS2008 software from ebay, installed and upgraded to NIS 2009. The registration was 1 yr and is now expiring.  I am registered on Norton Accounts.

I recenetly purchased another NIS2009 software/key for a 2 yr license from ebay to update my current software.

Is  it possible to just update theold key with the new license key or do I have to reinstall and then eneter the new key?

 

Thanks
