How to Migrate Your Minecraft Server to a New Host Without Losing Data

Switching hosts is stressful when your world, player data, and plugin configs represent months (or years) of work. Follow this process to migrate safely.

Step 1: Take a Full Backup First

Before touching anything, download a complete backup of:

• The world, world_nether, and world_the_end folders (or your world name equivalent)
• The plugins folder, including each plugin's config subfolder
• server.properties, whitelist.json, ops.json, banned-players.json, banned-ips.json
• Any custom datapacks or resource packs

Do this even if your current host claims to auto-migrate for you. Never rely on a single copy of your world existing in only one place during a migration.

Step 2: Set Up the New Server (Don't Start It Yet)

1. Create the new server instance on your new host at the matching Minecraft version and server jar (Paper/Purpur/Forge/Fabric) as your old one.
2. Upload your world folders and plugins before first boot.
3. Copy over server.properties settings you rely on (gamemode, difficulty, MOTD, etc.).

Step 3: Do a Test Boot Privately

Start the new server with the old world loaded, but keep it off the public IP/DNS for now:

• Confirm the world loads without corruption errors in the console
• Check /tps and general stability for a few minutes
• Verify plugins loaded correctly and player data (balances, ranks, claims) is intact

Step 4: Freeze the Old Server Before Final Sync

Announce a short maintenance window, stop the old server, and take one final backup of the world folder — this captures any changes made between your first backup and the cutover.

Step 5: Cut Over DNS/IP and Announce

Update your server address (A record, SRV record, or shared IP in your Discord) and let players know. Keep the old host active for a few days as a safety net in case anything needs to be pulled from it.

Common Migration Mistakes

• Forgetting usercache.json and per-player data files in world/playerdata
• Migrating to a different Minecraft version without checking plugin compatibility first
• Not testing the new server privately before pointing players at it

RepublicNodes support can help walk through a migration and includes automated backups on every Minecraft hosting plan, so you always have a safety net during a move.
