They're not compatible, and reworking the Nost code to work would be the same as just starting from scratch with what they have remaining, and having to rework the entire system to what they think was happening 11 years ago - and if the code was poorly documented, it's even more work.
Some of the more stubborn posters here hold Blizzard to unreasonable standards for data retention, expecting them to hold every scrap of code, every change, every iteration of their databases, forever - and expect them to have seen their code as something that would need to be reused a decade later, back in 2004. That's just...laughable. They didn't even know if WoW would be around another 10 years, so when they overwrote data in the databases, what used to be there didn't matter.
But none of this will matter - they'll still throw tantrums and insist that it's easy, or that Blizzard is lying, or that the guesswork Nost did can just be copied and pasted onto a live Blizzard server. It's the same mentality and childish tantrum throwing that has fueled this thread from page one.
