HaruHostPick it when you create the server
The version step lists Preaquatica and Latest. HaruHost downloads the server on that branch, on Windows and Linux.
Switch later
- Open the server's Details tab.
- Next to Branch, choose Change branch and pick the version.
- Press Update. Changing the branch only sets the version; the update downloads it.
- Start the server.
Players on the same version
A player on Preaquatica can only join a Preaquatica server, and a player on the latest version a Latest server. In Steam, players choose the branch in ARK: Survival Evolved's Properties → Betas.
Every map of a cluster
Put every map of a cluster on the same version, so players can move between them.
Questions
Why can't my friends see or join my Preaquatica server?
Their game is on another version. They choose Preaquatica under Betas in the game's Steam properties, or you switch the server to Latest.
Does switching the branch keep my world?
The world stays in the server's saves when the branch changes. Make a backup first in case the other version can't load it.
