This next plugin is a great tool for anyone building or migrating a WordPress site. As we know, WordPress sites are all based on databases that are usually created just for them.
Better Search Replace (BSR) allows the user to search all or certain tables in their database for a word or words and either erase them or change them to something else. If a company with a WordPress website was just purchased by another company and the name was changed, no problem. This plugin can find all instances of the old name and replace each one with the new name.
