I have InDesign CS6 for mac, which is an upgrade from CS5, which was also an upgrade from CS3 full.
I wan to transfer the lot to someone else. What do I do? I know about the licence transfer form - which serial number do I use?
I chatted to customer service, but they didn't seem to understand at all - they just said that I couldn't transfer an upgrade (which makes sense).
Let me see if I understand this, you are trying to sell the upgraded InDesign CS6 (which was an upgrade from CS5 [upgraded from CS3])? You would not be able to sell the InDesign CS6, CS5, or the CS3 upgrade individually, since they are considered one item, so they would all have to be included in the sale. It is true that you can't separate the version you used to upgrade from the upgraded version for selling purposes, because they are a single entity, but the End-user licence agreement does not mention if you are able to sell the entire upgraded package.
I would ask Adobe if you are able to sell the InDesign CS6 upgrade, understanding that it needs to include the CS5 upgrade and CS3, since CS3 was used to upgrade to CS5, which was upgraded to CS6. I hope that helps.
