What problem does it solve?
This skill helps you implement safe, version-controlled migrations for Foundry VTT modules when changing data structures or storage locations, ensuring data integrity across updates.
Core Features & Use Cases
- Safe migration patterns for moving data between storage locations, transforming data structures, renaming fields, and removing deprecated data.
- Schema-versioned migrations with an idempotent workflow that runs once per world.
- Batch updates and robust testing, with utilities and patterns for handling embedded documents, flags, and system fields.
Quick Start
Trigger migrations by calling Migration.migrate() in the browser console or reloading a world to run the ready hook. This guides you through validating old-to-new data mappings and verifying that the schemaVersion increments correctly.
