As mobile applications evolve, database schemas often need to change to accommodate new features or fix issues. Managing these changes without disrupting the user experience is critical.
Mobile databases support versioning to keep track of schema mobile database changes. When an app updates, migration scripts can modify the existing database structure—such as adding or removing tables and columns—without data loss.
Proper migration planning ensures backward compatibility and prevents app crashes or corrupted data. Some mobile databases provide built-in tools to simplify schema migration, while others require custom scripts.
Developers should thoroughly test migrations across different versions to guarantee smooth upgrades and maintain data integrity.
