Mod ViaVersion

ViaVersion, Connect Newer Clients to Older Servers

ViaVersion is primarily a Minecraft server plugin for Java Edition that translates network protocols, allowing newer clients to join an older server without forcing the server to update. This is useful for communities that want to preserve an established map, plugin setup, or gameplay experience while welcoming players using different game versions.

Its protocol translation layer handles differences in packets, items, entities, and other connection data. It supports platforms such as Paper and Velocity, with related Via projects extending compatibility to other software. It adds no new content and does not replace the server’s core gameplay. At BoxToPlay, we see it as a practical way to keep a Minecraft server accessible across versions.
