There are some very major changes to the database schema between the
1.4 and 1.5 branches of MediaWiki. As has been recommended, check the
upgrade notes, check any documentation lurking about on Meta
(
http://meta.wikimedia.org) and if in doubt, come into the #mediawiki
channel (
irc://irc.freenode.net/mediawiki) and ask.
As ever, back up both files and the entire MediaWiki database prior to
taking any action whatsoever. It is apparently very easy to mess up
this upgrade process, according to some reports.

Hi,
If I want to upgrade my wiki from 1.4.9 to 1.5 stable, would I treat it
as a standard upgrade within versions? I.e. would I just copy over the
files and load up the wiki home page?
This information wasn't so clear in the documentation, so I thought I'd
check in with the list.
