I've been tasked to migrate a MediaWiki install (V 1.5.6) to a new server. I suppose I could just install the older version but I'd rather migrate if it's possible. Is the jump from 1.5.6 to the current 1.18.0 too big a jump? I was planning on dumping the database from the old server and importing to the new if that is possible. I don't have a lot of experience here but if that will then I should be able to copy in all the images from old to new and be pretty much done. This wiki doesn't have any add-ons, just a basic wiki for some of my users to collect and share information.
Dont try to import an old dump into a new version, upgrade to the new version and then dump, or install the old version on the new server and then upgrade.
Few more details mentioned here: http://www.mediawiki.org/wiki/Manual:Moving_a_wiki
