Change version of a server keeping world and everything

[ValeMelis]

I have one of my servers on 1.21.1 how do I bring my server to a newer version?

If you have package set: Change package to a newer version, such as package = pkgs.minecraftServers.vanilla-1_21_4;

If you do not have package set: Run nix flake update nix-minecraft or similar, as your pin of the flake may be out of date.
