MisesWiki:Upgrading

Mises Wiki generally upgrades its MediaWiki installation whenever a new version comes out.

Procedure

Make a backup of the database and file system by following instructions at MisesWiki:Backups.
Go to https://www.mediawiki.org/wiki/Download and get the URL for the newest download. (Or, if you're downloading from Git, use git clone https://gerrit.wikimedia.org/r/p/mediawiki/core.git.)
wget that URL.
tar xvzf mediawiki-1.xx.x.tar.gz -C /home/web/public_html/wiki
The following must be recursively copied into the new directory (/home/web/public_html/wiki/mediawiki-1.xx.x) from the old directory:

images folder
extensions folder
LocalSettings.php
The custom Mises Wiki skin (Vector.php, Vector.printable.php) and any dependencies (e.g. the Mises Wiki shield image); for the dependencies, you may as well just use cp -r /home/web/public_html/wiki/mediawiki/skins/misesskin /home/web/public_html/wiki/mediawiki-1.xx.x/skins

In addition, chgrp and/or chown should be run recursively on the images folder to make those directories writeable by users in the "web" group. I guess that would be chgrp -R web /home/web/public_html/wiki/mediawiki/images/* and chown -R web /home/web/public_html/wiki/mediawiki/images/*
Also upgrade the extensions:
