-# Database Migration
-
-The database migration is an upcoming refactor to TagStudio's library data storage system. The database will be migrated from a JSON-based one to a SQLite-based one. Part of this migration will include a reworked schema, which will allow for several new features and changes to how [tags](../library/tag.md) and [fields](../library/field.md) operate.
