Migrating from Old L5R4 System

If you're coming from the original l5r4 system v12 or any 1.x version, you'll need to migrate. The system ID changed from l5r4 to l5r4-enhanced, which means Foundry treats it as a completely different system.

Migration Tool: Install this module in both your old and new worlds:

https://github.com/ernieayala/l5r4-migrator/releases/latest/download/module.json

Steps:

1. Export data from old world (the module auto-detects your schema)
2. Create new world with l5r4-enhanced
3. Import data (auto-converts to new format)
4. Check your actors, items, scenes, journals

Problems? See the Migration Guide for detailed instructions and troubleshooting.
