So I asked TyAand here is reply :

"Links to existing forum threads will redirect to their Discussions equivalent. We are planning on migrating existing forum content to discussions when the migration happens.

Yes, on the replacement for Forum you will be able to comment and post threads on it."

So no, no forum threads will be deleted, everything will be migrated from to the Threads system to the Discussion system.
