Better Search Replace Plugin

When moving your WordPress site to a new domain or server, you will likely run into a need to run a search/replace on the database for everything to work correctly. Fortunately, there are several plugins available for this task, however, all have a different approach to a few key features. This plugin consolidates the best features from these plugins, incorporating the following features in one simple plugin:

• Serialization support for all tables
• The ability to select specific tables
• The ability to run a “dry run” to see how many fields will be updated
• No server requirements aside from a running installation of WordPress
• WordPress Multisite support

Time-saving features available in the Pro version:

• View exactly what changed during a search/replace
• Backup and import the database while running a search/replace
• Priority email support from the developer of the plugin
• Save or load custom profiles for quickly repeating a search/replace in the future
• Support and updates for 1 year

The search and replace functionality is heavily based on interconnect/it’s great and open-source Search Replace DB script, modified to use WordPress native database functions to ensure compatibility.
