Hello, I am not a staff, but I can answer it for you, as of what I have understood.
Mineapoc and Noobstown is merging (as you probably know) and Mineapoc is becoming it's own world, known as Dungeons. All progress from Mineapoc WILL transfer over to the Dungeons world, including ranks. If you have bought VIP since they made it permanent, you will get your VIP rank into Noobstown. If you maybe bought VIP in Apoc and VIP in Noobstown, you'll get VIP+ (not so sure on this one).
