Cryptsy disappeared in January 2016, but if memory serves me correctly, ADT was under maint for months and months before then.
This is a very old thread - the ADTv2 one is here: https://bitcointalksearch.org/topic/m.4838148
The swap needed to be user initiated (I believe it was a website) so people with ADTv1 coins will not automatically have that balance transferred to the ADTv2 blockchain. Therefore, if the Cryptsy wallet is ADTv1 (not sure if they ever changed to v2) it is most likely worthless. Unless there's some merge of v1 and v2 into a new v3 blockchain (the new blockchain would be required in order to fund the v1 addresses)
all exchanges were swapped to v2 as well as a good chunk of user holdings from memory we swapped over around 50,000,000,000 from the 68,000,000,000 total and were still getting a good amount of swaps when cryptsy caused the fork
