Upload your own Minecraft world

Bring your Java Edition world to your OXY.Games server without losing the existing world. You can start with a singleplayer save or a download from another host.

What you'll do

1. 1Get a complete copy of the world
2. 2Back up and stop the OXY server
3. 3Upload the world files
4. 4Select the world and check it in-game

Keep a copy before replacing anything

Make a backup of your OXY server and keep the original world download on your PC. Stop both servers before copying their files. Check that the Minecraft version and any required mods match; see change your server version.

How to upload a singleplayer world

1. Make a copy on your PC

   In Minecraft Java Edition, open Singleplayer, select the world, choose Edit → Make Backup, then Open Backups Folder. Keep the original .zip as your safety copy. Unzip a copy on your PC and find the world folder containing level.dat. Minecraft’s backup instructions show these controls.

2. Back up and stop your OXY server

   Create a panel backup, then click Stop on the Console page. Check the current level-name in server.properties. In Files, rename the existing world folder to a name such as world-before-upload if it is present. If world_nether and world_the_end exist, rename those too so your upload cannot mix with the old world. Leave a current world with a different name untouched.

3. Upload the new world

   Name the extracted folder world, zip that folder, then use Upload in Files and Unarchive on the zip. Check that world/level.dat is visible in the server’s root folder, not world/world/level.dat. The file manager accepts files up to 100 MB. If the zip is larger, transfer the folder or zip with WinSCP or FileZilla via SFTP; the SFTP guide shows where to find your address, username and password. Unarchive an uploaded zip in Files.

4. Select and test the world

   Open server.properties in Files and set level-name=world. Click Save Content, then Start. Wait for the console to finish loading and join your server. Check a familiar build and your inventory before inviting anyone else. If you see a new empty world, stop the server and check the folder nesting and level-name first.

Done! Your own world is live

Keep your PC copy until you have checked the world in-game. You can download your world again whenever you want another copy.

How to transfer world and playerdata off of other server hosting company to this one?

Match the server software before transferring

Check the old host’s server software as well as its Minecraft version and required mods. The steps below keep the folder layout intact only when the OXY server uses the same software. If you are changing between Vanilla, Paper, Forge or Fabric, follow the relevant steps in the Paper migration guide before uploading. A direct Paper-to-Vanilla copy can leave the Nether and End in the wrong folders.

1. Download the complete world from the old host

   Stop the old server. At Shockbyte, BisectHosting, mc-node, Aternos, Kaas, Seedloaf or another host, download the world through their file manager or SFTP. Keep the whole world folder, including level.dat and any playerdata or players folder. If the host offers an archive, unpack a copy to inspect it. For older Paper worlds, include world_nether and world_the_end if they exist. Ask the old host for a full world export if you cannot access all folders.

2. Back up and stop the OXY server

   Make a backup and click Stop. In Files, rename any OXY world folders that would have the same names as the incoming folders. Do not merge the two sets of files.

3. Transfer and select the world

   Upload the exported folder or archive to the server root with SFTP, or use Files and Unarchive for an archive under 100 MB. If the server software matches, keep the downloaded folder structure intact; otherwise, use the migration instructions above first. In server.properties, set level-name to the name of the uploaded overworld folder; click Save Content. For example, if the folder is world, use level-name=world.

4. Start and verify the move

   Click Start, wait for the console to finish loading, and join the server. Visit a known build, check your inventory, and enter the Nether or End if you transferred those dimensions. If progress is missing, stop the server and compare the downloaded folders with the uploaded ones before changing anything else.

Done! Your old server’s world is on OXY

Keep the export from the old host until you have checked builds, dimensions and player data on the new server.

What are world, world_nether and world_the_end?

world is the main world folder named by level-name in server.properties. On older Paper servers, before Minecraft 26.1, world_nether holds the Nether and world_the_end holds the End when the main folder is named world. Keep all three when moving an older Paper world. A singleplayer or vanilla world from those versions instead keeps its dimensions inside the main folder as DIM-1 and DIM1; Paper handles a vanilla-to-Paper move when it starts. See the Paper migration guide.

From Minecraft 26.1, the default dimensions are inside the main world folder under dimensions/minecraft/, and player data is under players/data instead of playerdata. Keep the entire folder rather than looking only for the old three-folder layout. See the Minecraft 26.1 world-storage changes.

Extra tips

• The wrong world loads: Check level-name and confirm that level.dat is directly inside the folder it names; see Minecraft troubleshooting.
• Player progress is missing: Compare the source and destination world folders, including playerdata on older worlds or players/data from 26.1 onward.
• The upload is too large: Use SFTP when an archive exceeds the file manager’s 100 MB per-file limit.
