# v4.3.6 to v4.3.8 migration guide

The Strapi v4.3.6 to v4.3.8 migration guide upgrades v4.3.6 to v4.3.8. The migration changes the SQLite database package from sqlite3 to better-sqlite3. The migration guide consists of:

  • upgrading the application dependencies,
  • changing the sqlite3 package to better-sqlite3,
  • reinitializing the application.

✋ CAUTION

  • This migration guide skips v4.3.7, which introduced an error in the SQLite database.

  • Plugins extension that create custom code or modify existing code, will need to be updated and compared to the changes in the repository. Not updating the plugin extensions could break the application.
