Updating paper

[Duma0064]

I am currently playing on a 1.20.4 paper server. I thought it would be like vanilla. I were really wrong since I couldn't do tnt duping and such. So I fixed that in file config. My problem starts at portal duping. I tried everything in the config file to make it work, and it didn't. After a long while I went to paper discord server. They noticed that my paper version were 53 updates behind. So I downloaded the newest paper version, deleted the server.jar and replaced it with the new paper file renamed it to server.jar. That should have been everything I must do to update the paper. But then this post would never been made. How does one update the paper version which I do really need, 53 updates behind is quite a lot and I don't want to play with that when it won't work as I need it to.
