Thread:Project:Support desk/Multiple MediaWiki versions pointing to same database

I am taking over administration of a small MediaWiki site for my University help desk. It was fairly outdated (was running 1.15), and I am looking to modernize the database, and add increase its usability. Unfortunately, the database is on a server with multiple other help desk applications, and as the help desk is run by students, much of the server and its software was pieced together hastily when needed. The ser is currently in active use, and cannot be taken down. I am hoping to create a second "wiki" which points to the same MySQL database, but with different settings, extensions, etc. Thus far, here are the steps I have taken:
 * 1) I updated the wiki to MediaWiki 1.23.3
 * 2) I duplicated the the mediawiki folder   to   on the server
 * 3) I then added additional aliases to the apache.conf file, but the "alternate" wiki does not load (see http://pastebin.com/puwCh5H1) for Apache.conf)
