Sync Two MediaWikis weekly?

We have two 开发者_C百科mediawiki (like wikipedia) installations. One is public and one is internal.

We do the normal work with the internal adding/changing/deleting text articles and pictures.

We want to sync and update the external one on weekly bases, what is the best approach?

note: We are using 2 windows servers (but willing to change to linux (1 or 2 server setup) if that will make it easier)

cheers

As Kaestur Hakari writes, the content is in a database, so just make a database dump in an appropriate format from the first database and load that into the second one.
