Moving old website to new website template + functions

Hey guys,
Weird question: I have the Saigon website, however it is on a very much older version as compared to the Munich website, so much so that it is not worth it to keep anything in the older Saigon website apart from the community builder part of the website.

Now, how do I make it so that I basically get a clone of the munich website BUT keep all the community builder data (Only member data ie user data).

Just a copy of the database tables for community builder? How can I easily find them?

Link to website (new): munich.international-friends.net/ (old): saigon.international-friends.net/

CB Juice can be used to export from your old site then import into your new. We don't have an official migration method. If your user ids are kept intact between the sites then yes a direct database export and import will work. All CB tables begin with _comprofiler, all CBSubs tables begin with _cbsubs, and all GJ tables begin with _groupjive.
