Server updating problems

[Klonken321]

So im quite new to this FTB server hosting and last time i updated my server it didnt want to start again so i ended up making a new world, but today they launched a new version of the direwolf20 pack and i would like to know how to update the SERVER, since the client is just to press "update" and it'll update..

Hi, I'm getting the same issue on my server. I was able to port over my world by copy pasta'ing the world folder, but there are a whole slew of mismatched ids on my log. It seems that items like the nano saber won't function properly.
