so how is that "full functional" if there's other functions it doesn't do? "full" means "all" or "everything"

I upgraded to AD2 at XLN when it came out. It was the same thing. There was an offer to upgrade every old content for a specific cost.
But you don't have to do it. You can use the old stuff in AD1 and if you buy any new Adpaks, the AD2 engine is for free.

Same thing now with what you get with Sonar.

Do you get the difference?

I already had AD2 and the upgrade. But the AD2 Producer means, that you get 3 Adpaks and 3 MidiPaks... The engine doesn't cost anything. So I chose some more Paks. Still a great deal.

i think i get it - there's 2 upgrades, one for the engine (ad2) and a separate one for the (ad1) content

Actually it's only one upgrade. When you upgrade, the engine (AD2) remains the same, but the upgrade sends you (via the installer) new AD2pacs to replace the old AD1pacs that you previously purchased.

Yeah, I think that's about right - Platinum comes with AD2, not XLN's upgrade to AD2.

To the OP, why not install Platinum? Versions can co-exits and your membership starts when you place your order with CW so even though your did not install your 12 month membership clock is ticking.
 
And if you bought through a retailer you had to redeem your purchase to install AD2 and again, your membership clock would be clicking,
