Activating SI/ToA, CDkey question

[raid]

Is it possible to activate SI/ToA expansions on a existing, plain classic account using a box which has classic+si+toa? I know classic+si box had 2 separate CD-keys because I have one, but I heard classic+si+toa box contains only one CD-key for all 3 and the question is if it can be used to activate only the expansions.

Yes.
The single CD-Key is good for each of the expansions and the main game so if you use it to activate ToA on an existing account, you can still use it to activate Classic and SI on a new account or SI on a different account and a new classic account.

Nice, thanks for the fast response.
