Very simple plugin for migrating data from one site/blog to another. It is very good tool for doing this job with ease and faster. I am using better search replace pro in my website migration projects. This plugin helped me a lot while performing such tasks as moving content of the old blog into new one. The only thing which i dislike about this software is that sometimes due to some reasons, it might not work properly or even crash sometimes when you are trying to transfer something. You should try this if you want to move contents from an older version to newer version without much trouble. While transferring contents we found problems like missing posts etc so the best way was to use this plugin and everything worked fine.
