Not in a million years. 6.5 means you are on the original CS which is more than Adobe's current 3 versions back upgrade policy, meaning it would have to be at least CS3 to qualify for an upgrade. Your only option is to buy a completely new version.
I have been asking this question for the longest. Over a year really almost two years. It's hard to get help from adobe unless they hear the word purchase.
If you were asking it here, this is a user-to-user forum and not a way to contact Adobe. Did you call their sales team? They usually answer questions like that very quickly and easily.
