Generally speaking ticket upgrades are a 1:1 basis -- 1 "old" ticket towards 1 "new" (upgraded) ticket. I'd say you probably received some pixie dust by upgrading an existing AP
and rolling another ticket into that upgrade. I'd be highly surprised if you could have rolled additional tickets into that as well, but since it seems to have been outside the normal scope it's possible that CM would have done so. However I would not recommend that anyone
expect to be able to combine multiple tickets, whether for an upgrade or a new voucher

My aim was to help folks in my situation (DVC & FL resident) understand that they need to call and not try it on the website. If you are a dvc member, you can call dvc and the will transfer the call to ticketing department. Because I have everything scheduled, ticketing asked “which of the tickets, in addition to the upgrade, was I going to use towards the Sorcerer”. I interpreted this to mean I could use my tyhoon lagoon after hours, or epcott tickets. It wasn’t luck nor special treatment. I was told by them that anything over the use of one ticket or annual pass has to go through ticketing. Ticketing has the ability to upgrade the AP using annual passes and tickets (not vouchers).
