[Plugin: Facebook Comments to WordPress] Need help regarding the plugin

I am using facebook comments social plugin. I want to use livefyre now. But want to retain the facebook comments posted on post.
That means ==> I want to import facebook comments posted on blog posts into wordpress database. Livefyre automatically takes care to read comments from database.
Is this the right plugin for that?
What do I need to take care of while importing all blog-posts comments in wordpress database?

Thanks
