Migration from v1-legacy to v2

GWorld v2 features intelligent migration systems that make the transition from older versions or the change between storage media (files to database) as easy as possible.

 Migration from GWorld v1 to v2 
 When you upgrade from the first version of GWorld to v2, the plugin will automatically detect this during the first start. 
 How it works 
 Detection: The plugin looks for an existing worlds.yml where... the ConfigVersion field is missing the LoadWorlds list exists the Worlds list exists Automatic Backup: Before changes are made to the datasets, GWorld renames the old file to worlds_legacy_backup.yml . Data Conversion: The LegacyMigrator reads all old world definitions and transfers them into the new, structured v2 format . Missing new fields are filled with default values. Seed Repair: Since seeds were not saved in v1, GWorld v2 automatically detects missing seeds when the world is first loaded, reads the correct seed from the world files, and corrects the entry. 
 Note: During the migration, the console will inform you about the progress. Once the worlds.yml file contains a ConfigVersion: 1 , the process is complete. This will also be output in the console. 
 After a successful migration, GWorld v2 starts normally and all worlds are loaded. 
 Security Measures & Prerequisites 
 To ensure a smooth migration, please note the following points: 
 Prerequisites (see Introduction ) 
 Java Version: GWorld v2 strictly requires at least Java 21 , as modern language features are used. 
 Checklist 
 Create a manual backup of your entire plugin folder before upgrading. After the migration, check with the command /gworlds whether all worlds are listed correctly. Check the server console for error messages during the first start.
