Just started your Minecraft server, but that one friend who doesn't have a Minecraft account wants to join? Or maybe you're switching your server from Online Mode to Offline Mode (or vice versa)? UuidMigrate makes it effortless to transfer all player data between Online and Offline UUIDs!
Features: • Auto-Migration - Automatically detects and migrates player data when they join • Safe & Secure - Creates automatic backups before any changes (default: COPY mode) • Fully Configurable - Choose exactly what to migrate (inventory, stats, advancements, custom paths) • Smart Detection - Automatically finds world folders, handles Nether/End dimensions
Perfect For: • Servers switching between Online/Offline mode • Friends without Minecraft accounts wanting to play • Migrating legacy player data • Mixed authentication server environments
Limitations: • Permissions data will not be automatically migrated (requires manual setup as of now) • Some plugin settings may need manual configuration • Request specific plugin support on our Discord server!
