[xwiki-users] Merging xwiki databases

I have two xwikis running on two different servers, with different databases. I want to centralize those xwikis in only one server. Therefore, I'm looking for a way (or a tool) to merge the information present in the xwiki on the server that will be disabled, into the database of the xwiki running on the central server, that will remain active. The structure of the old wiki will remain the same, and will be accessed from a link at the main page of the xwiki that will remain active. Does anyone know if it is possible to do that?! If it is, how can I accomplish this? Thanks a lot, Roney Castro
