The war between malware writers and antiviral developers is an ongoing one. Software written ten years ago, no matter how great at the time, would not be close to competent to deal with today's family of malware.
Occasionally, change happens fast and a developer has to decide whether or not to try to accomodate old versions to the new problems or simply to offer a new product as a free upgrade, a product that does deal with the new threats.
I can't swear that that is the case here; but it would not surprise me. If Symantec were to charge for the upgrade, that would be a different issue; but the upgrade simply takes the old product key and remaining subscription time and uses that. In that sense, it would be appropriate to say that NIS 2009 is THE FIX for the problem you are describing (assuming, of course, it really is).
Hoping things work out for you,
