Content Migration or Restoration of UserProfile App Service to New

Anyone know how to properly rebuild a jacked up UserProfile Application Service so that the existing social data, etc is restored to a clean UserProfile Service Application?  I'm attempting to utilize the Replication Engine Toolkit but having no luck.

(I don't want to overload you with why this needs to be done, just need some ideas of how to retain the existing UserProfile content)

Thanks in Advance.
