You can upload an existing Minecraft Java world to your Down Side Hosting server using the server panel.

This is useful when moving a single-player world, transferring a world from another host, restoring a backup, or moving an existing Minecraft server to Down Side Hosting.

Important: Stop the Minecraft server before replacing or uploading an active world. Uploading files while the server is running can cause world data to become inconsistent or corrupted.

You should have:

• Access to your Down Side Hosting server panel
• Your Minecraft Java world folder
• Enough available server storage
• A backup of the existing server
• The server stopped before replacing world files

If you are moving a server from another host, download a complete copy of the world before beginning.

Minecraft Java single-player worlds are normally stored in:

%appdata%\.minecraft\saves

Press:

Windows Key + R

Enter:

%appdata%\.minecraft\saves

and press Enter.

Each folder inside the saves directory normally represents one Minecraft world.

On an existing server, the main world is commonly stored in a folder such as:

world

However, the folder name can be changed.

Check your:

server.properties

file for:

level-name=

For example:

level-name=world

means the server expects the main world folder to be named:

world

A Minecraft Java world folder normally contains files and folders such as:

level.dat
region
data
playerdata
advancements

Not every world will contain exactly the same folders, but level.dat is one of the most important files to look for.

A common mistake is uploading an extra folder level.

For example, this is incorrect:

world/
    MyWorld/
        level.dat
        region/

if the server expects world itself to contain the Minecraft world.

You generally want:

world/
    level.dat
    region/
    data/
    playerdata/

Open your Down Side Hosting server panel.

Select your Minecraft server and click:

Stop

Wait until the server has completely stopped before modifying the world.

Do not simply disconnect from Minecraft. The actual server process needs to be stopped.

Before replacing a world, make a backup.

If your current world folder is:

world

you can rename it to something such as:

world-backup

or:

world-old

You can also use a server backup if one is available.

Keeping the previous world temporarily makes it much easier to recover if the new world does not load correctly.

For larger worlds, it is usually easier to compress the world folder before uploading it.

For example:

my-world.zip

Make sure the archive contains the actual Minecraft world files.

For example:

my-world.zip
    level.dat
    region/
    data/
    playerdata/

Avoid accidentally creating unnecessary nesting such as:

my-world.zip
    my-world/
        my-world/
            level.dat

Open the Files section of your Down Side Hosting server panel.

Upload your world archive or world files.

For example:

my-world.zip

Large worlds can take some time to upload depending on the size of the world and your internet connection.

If you uploaded the world as an archive, extract it using the server panel.

After extraction, verify that the world folder contains:

level.dat
region/
data/

and the other Minecraft world files.

For example:

my-world/
    level.dat
    region/
    data/
    playerdata/

There are two common ways to make Minecraft load the uploaded world.

If your server already has:

level-name=world

you can rename the uploaded world folder to:

world

Make sure the old world folder has already been renamed or backed up first.

You can instead change:

level-name=

to match your uploaded world folder.

For example, if your folder is:

survival

set:

level-name=survival

Save the file before starting the server.

Paper, Purpur, and Spigot servers can organize dimension folders differently from a standard Vanilla world.

You may see folders such as:

world
world_nether
world_the_end

If you are moving an existing Paper, Purpur, or Spigot server, it is usually best to transfer all of its existing world folders together rather than uploading only the Overworld.

This can include:

world
world_nether
world_the_end

The exact names depend on your server configuration.

If you are moving between different Minecraft server software, make a complete backup before changing the world structure.

Return to the server console and click:

Start

Watch the console while Minecraft starts.

A successful startup should eventually show that the server is ready for players.

If Minecraft creates a completely new world instead of loading your uploaded world, stop the server and check:

• level-name in server.properties
• The uploaded folder name
• Whether level.dat is in the correct folder
• Whether there is an extra nested directory

Connect using your Down Side Hosting server address:

dsh.network:YOUR_PORT

Replace YOUR_PORT with the port assigned to your server.

After connecting, verify:

• You spawned in the expected world
• Player inventories are present if they were transferred
• Builds are present
• The Nether loads correctly
• The End loads correctly
• Plugins or mods work correctly
• No major errors appear in the server console

How to Connect to Your Down Side Hosting Minecraft Java Server

If Minecraft generates a new world, the most common cause is that the server cannot find the world specified by:

level-name=

For example:

level-name=survival

requires a folder named:

survival

Check that the actual structure looks like:

survival/
    level.dat
    region/

and not:

survival/
    survival/
        level.dat

First make sure Minecraft loaded the correct world.

Check:

server.properties

and verify the level-name setting.

You may have accidentally:

• Uploaded the wrong world
• Used the wrong folder name
• Created an extra folder level
• Started the server before the upload was complete
• Uploaded only part of the world

Stop the server before making additional changes.

If the Overworld transferred correctly but the Nether or End did not, check whether the old server used separate dimension folders.

Paper, Purpur, Spigot, and similar server software may have folders such as:

world_nether
world_the_end

Make sure all required world folders were transferred.

Yes.

A Minecraft Java single-player world can normally be uploaded to a server.

Locate the world in:

%appdata%\.minecraft\saves

Then upload the desired world folder to your server.

You may need to rename the folder or change level-name in server.properties before starting the server.

Yes.

Before leaving the previous host, download a complete copy of:

• The main world
• Nether world
• End world
• Plugin data if needed
• Mod data if needed
• Server configuration files if you are migrating the entire server

For a complete server migration, transferring the entire server installation is often preferable to transferring only the world.

No.

Keep the old world or a backup until you have confirmed that:

• The uploaded world starts correctly
• Your builds are present
• Player data is present
• Nether and End dimensions work
• Plugins or mods work
• The server has restarted successfully

Once you are confident the migration is successful, you can remove unnecessary backup files to recover storage space.

Down Side Hosting supports Minecraft Java servers including Vanilla, Paper, Purpur, Spigot, Forge, Fabric, plugins, mods, custom worlds, and server migrations.

Minecraft Java hosting starts at $2/month.
