I guess this is the official installation guide: Manual:Installation guide.

Note that I have not used it myself. When I install MediaWiki, I extract the files from the tarball into the according folder. So basically into that folder where you before had the old 1.19 version installed (and before I extract the files I empty this folder). After extraction, I would call the wiki URL with my web browser and go through the installation process. At the end, I would download the LocalSettings.php file (which is offered then) and would put it into that folder as well. :-)
