It throws a net.sqlcipher.database.SQLiteException: file is not a database.\n\n- The password is the same\n\n- The database file is preserved\n\n- Migration fails silently or throws an error\n\nWhat is the correct way to migrate an existing SQLCipher-encrypted Room database from SafeHelperFactory to SupportOpenHelperFactory while preserving the data.\n\nThanks.","author":{"url":"https://github.com/viethoangtien","@type":"Person","name":"viethoangtien"},"datePublished":"2025-07-15T16:30:37.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/66/sqlcipher-android/issues/66"}
