Hi. I'm afraid that Wikia isn't really suitable to what you are looking for as it isn't possible to create private wikis. Additionally, Mediawiki is not really intended as a content management system, so it is worth bearing warnings like this in mind.

Although you may not wish to do so given the above, you can import the information from a .xml format using Special:Import, although I'm not sure if having a different version of Mediawiki could cause problems.

I would recommend either looking for another host that offers what you are looking for, or host it on your own server.
