It is designed to handle complex data structures, including serialized arrays and JSON objects, ensuring your data remains uncorrupted during migrations or domain changes. **Key Features:** * **Safe Serialization Handling**: Automatically detects, unserializes, replaces, and re-serializes data to prevent breakage. * **JSON Support**: Safely handles JSON encoded strings within your database. * **Dry Run / Preview**: Test your replacements before applying them. See exactly what will change with a „Diff” view. * **Deep Linking**: Preview results include direct links to the affected Posts or Pages (for viewable content). * **Backup Integration**: Automatically creates a SQL backup of affected tables before running a live replacement. * **Undo Capability**: Rollback changes instantly if something goes wrong. * **Primary Key Batching**: Uses efficient ID-based batching to handle massive tables without timeout. * **CSV Export**: Export your preview results for offline analysis. ## Installation 1. Upload the plugin files to the `/wp-content/plugins/bytefyre-db-replace` directory, or install the plugin through the WordPress plugins screen directly. 2. Activate the plugin through the ‚Plugins’ screen in WordPress. 3. Navigate to **Tools > ByteFyre DB Replace** to start using the tool. ## FAQ ### Is this safe for serialized data? Yes. ByteFyre DB Replace specifically checks for serialized strings, unserializes them, performs the replacement, and re-serializes them. This ensures that string lengths are updated correctly. ### Does it support multisite? It supports running on individual tables. You can select all tables in a multisite environment, but you must be a Super Admin to access the tool. ### Can I undo changes? Yes. The plugin keeps a log of recent operations and allows you to „Undo” changes by restoring the backup taken immediately before the operation. ## Reviews ![](https://secure.gravatar.com/avatar/593b54bd402d908395ca9322b401152020209cd553d51a96c8c8c32342827194? s=60&d=retro&r=g) ### 󠀁[Simple, Fast and Does the Job Perfectly](https://wordpress.org/support/topic/simple-fast-and-does-the-job-perfectly/)󠁿 [nehalkumar82714](https://profiles.wordpress.org/nehalkumar82714/) 1 kwiytnia 2026 I tried a couple of DB replace plugins before this, but this one feels the most stable.
