Thread:Project:Support desk/Migrating data from multiple MediaWiki servers to a single MediaWiki server

My current employer has 3 different MediaWiki servers that they want to migrate into a single MediaWiki server.

What is the best way to do this? Is there some kind of utility available to download that can handle the migration process?

I have seen that MediaWiki has functionality to export pages, but I want to export the contents of the entire wiki, including all users, categories, images, links, history, etc not just a few pages at a time.
