What happens upon migration to N2?

[vk]

I've got a large list of favorite forums on N1 - does this mean I'll lose them all when you disable N1 and make us move to N2? (That'd suck big time)

Also, since forums are either N1 or N2 forums, when I'm on N2 will I still be able to access the N1 forums I used to access?

Thanks!
