PBR
-
Can I search specific database tables only?
-
Yes, you can select which database tables to include in your search and replace operations.
-
Is it safe to use this plugin?
-
Yes, when used properly. The plugin includes multiple safety features and warnings, but you should always backup your database before performing any search and replace operations. The plugin will remind you to do this.
-
Will it break serialized data?
-
No. The plugin unserializes, replaces, then re-serializes values so data remains valid.
-
Can I undo changes made by the plugin?
-
The plugin doesn’t have a built-in undo feature, which is why backing up your database beforehand is crucial. The detailed reports can help you understand what was changed.
-
Does it work with multisite installations?
-
Yes. Network admins can target any site tables; sub-site admins are limited to their own tables.
-
Will it work with large databases?
-
Yes, the plugin is optimized for large databases using batch processing and memory-efficient techniques. However, performance depends on your hosting resources. In some cases (especially on low-memory or shared environments) it may not be possible to complete the process reliably.
-
What happens if the process times out?
-
The plugin has built-in timeout management in the search phase and can automatically resume where it left off.
