I am running a modded minecraft server 1.21.1 with Neoforge 21.1.217 but I wanted to upgrade the RAM and the only way to do that is to start a new server with more RAM. I initially copied all the files from the old server to the new one but it would not let me join and would fail occassionally. I reset the server back to defaults and it was able to run on a new world with mods, but whenever I try to add the old world to the server I can load in but there are no chunks generated but I am able to access my inventory for about a minute until the connected is "Timed Out"
Does anyone know how to resolve this issue? Any help will be appreciated
