Japanese servers question ❓

With Conan upgrading to 3.0 I wanna ask something.
I’m playing on a Japanese server but I’ve read that Japan ain’t getting the upgrade just yet.
Am I going to be able to play after my system upgades or do I have to not upgrade to 3.0❓

Ok, I have upgraded to 3.0 but now I cannot enter my asian server. When will they get the upgrade?
