What does one do with an earlier serial number of Alloy 2

U took the leap huh bapu? :) Good for you
 
It's an incredible deal and someone should be BEGGING to buy it off of you IMO

I jumped on the Music Production Bundle deal, you couldn't really pass that by, I already owned Ozone 5, Ozone 5 Advanced, Ozone 6 Advanced, Alloy 2, Nectar 2 Production Suite and Insight. Still it really was a no brainer, I get the upgrade to Ozone 7 Advanced and Trash 2 and 2 expansion packs (and the rest of the bundle) for $209, take away $100 for Trash 2 (and expansions) and that's $100 to upgrade to Ozone 7 Advanced, pretty sweet deal if you ask me. Trash 2 is pretty awesome on it's own, very useful.
 
What to do with your extra serial ? up to you, I'll keep mine, you never know if you will run into problems with needing extra authorizations, probably unlikely but . . or perhaps you will want to run 2 instances at the same time which you are not legally allowed to do with only one license. I never sell anything anyway

It's worth fifty bucks or more if you post it on kvr. If you let go of the new S/N rather than the old one, your buyer won't even need to do a license transfer.
 
Or you could earn some good karma by giving it away to some deserving soul. (No, not me; another generous person has already done that for me. He knows who he is and knows how grateful I am for that act of kindness.)
